What to wear to jiu-jitsu, before you buy anything

Ask about the booked class before the uniform

Find the class name on your booking and check whether it says gi or no-gi. If it says only jiu-jitsu, ask. A beginner introduction can have its own arrangement, and a timetable may contain both formats. The gi versus no-gi guide explains the training differences; here, the immediate job is making sure your clothes match the session.

Published academy policies show why a direct answer matters. Valko BJJ’s FAQ recommends comfortable workout clothes for a first visit, ideally close-fitting enough for grappling, and says loan gis are available. It asks students who already own a gi to bring it for gi class. The same FAQ says its team apparel is optional. That is Valko’s policy, not permission to ignore another academy’s requirements.

Bellingham BJJ’s school policies allow any gi color or style and say a student may be able to borrow a gi for the first class or two. The conditional wording matters: it is a reason to ask about a loan, rather than a guarantee that a suitable one will be waiting. Its current policy routes incoming white belts through its introductory program, so visitors should also confirm the correct class.

A useful message names the appointment: “I’m booked for the beginner gi class on Tuesday. Do you have a gi and belt I can borrow in my size, and what should I wear underneath?” Add a question about a loan fee or reservation if the booking does not explain it. One short exchange can save an unnecessary purchase and a second trip home.

For gi, confirm the jacket, trousers, and belt

A BJJ gi includes a jacket and trousers, worn with a belt. For a trial, the academy should tell you whether it will supply those items or expects you to bring them. Check the belt as well as the gi. A clothing loan is less useful if you arrive assuming every piece is included.

If a loan is confirmed, ask when to collect it, whether it must be reserved, and where to return it after class. Ask how the academy handles cleaning. Do not take a borrowed gi home to wash unless that is the arrangement you were given. The important detail is that the equipment is ready for your session and returned as agreed.

If you already own a gi, describe it before the visit if you are unsure it is accepted. A gi for another martial art, a particular team patch, or a color permitted at one academy may need a different answer at the next. Avoid buying a replacement solely because you have seen another school’s students wearing matching jackets.

Try the approved gi before practice starts. You should be able to move through the class’s ordinary positions without a waistband coming loose or a jacket preventing movement. Ask the coach to check a doubtful fit. A size label helps when ordering; it does not tell you how that particular garment will sit on your body.

For tournaments, fit becomes a formal inspection question. The IBJJF uniform page specifies measurements for gi sleeves, trousers, and other parts of the uniform. A loan gi accepted for a beginner lesson has not automatically passed an event inspection. Keep those two decisions separate.

For no-gi, confirm both halves of the outfit

No-gi removes the gi jacket and trousers; it does not mean that any clothing will do. Ask which top and bottoms the class accepts. The useful description includes fit and construction, rather than only a brand name or the fact that something is sold in a sports shop.

10th Planet Burbank’s program gear list lists a rashguard and shorts or spats for its no-gi jiu-jitsu program. Its first-class guide tells trial visitors to check the program list and confirm equipment with the team before buying. The program-specific answer is more informative than treating “comfortable athletic clothes” as a complete uniform specification.

A rashguard is a fitted training top. Spats are fitted athletic leggings. Whether the academy accepts a plain fitted shirt, leggings alone, or shorts over leggings is a policy question to settle before the trial. If you have suitable-looking clothing already, describe it or ask whether the gym can check it when you arrive.

Check the waistband and coverage when you move. Stand, sit, and bend your knees in the clothes before packing them. If the top rides up or the bottoms slip during those ordinary movements, choose another approved option or ask the instructor. You do not need a wardrobe experiment halfway through a partner exercise.

Competition adds details that a trial may not require. IBJJF no-gi rules include rank-color and construction specifications. Those are reasons to check the current event documents if you enter an event, rather than reasons to buy ranked competition kit before a local introductory lesson.

Ask about layers under the gi

Under-jacket clothing is one of the easiest details to assume incorrectly. Ask the academy whether it requires or permits a fitted top beneath the gi, and what it accepts under the trousers. If you have a coverage preference, raise it before class so the instructor can explain the available arrangement.

Do not copy an event photo and treat it as a local dress code. On its published uniform page, IBJJF requires a body-hugging top beneath the gi in female divisions and prohibits an under-shirt in male gi divisions. Its rules also distinguish under-trouser garments. Those are competition requirements; your academy’s practice policy needs its own answer.

A question can stay practical: “Can I wear this fitted top under the loan gi, and are these leggings permitted underneath the trousers?” You can ask privately if that is more comfortable. The coach needs enough information to explain the policy, not a long account of why you prefer a particular layer.

Wear appropriate clean undergarments and check coverage before leaving the changing area. Avoid loose, dangling layers that you already know will need constant adjustment. If the clothing the academy requires does not work for you, discuss an alternative or a different class before paying for a uniform you cannot comfortably use.

Look closely at pockets and hard pieces

Turn the shorts over and inspect the waistband before deciding they are grappling clothes. Running shorts, gym leggings, and leisurewear can contain zipped compartments, decorative hardware, exposed fasteners, or pockets you have stopped noticing. Emptying a pocket does not remove its opening or its zip.

IBJJF’s no-gi uniform specifications prohibit items such as buttons, zippers, and other hard plastic or metal pieces on the relevant clothing. Its shorts rules permit no pockets or pockets that are completely stitched shut. This is a concrete competition example of why “athletic” is too broad a description on its own.

For a class, show an uncertain feature to the instructor and ask whether the garment is accepted. Do not assume covering a zip with tape or quickly tucking in a drawstring satisfies the policy. Bring a different approved option if the gym has asked for one. There is no need to turn a trial into a sewing project without first checking what is required.

Remove jewelry and hard hair accessories before partner practice, and ask how to manage anything you cannot readily remove. Put those questions to the academy before the visit so you know what arrangement is possible.

Check the fit before collecting more kit

Choose a garment that stays where it belongs during ordinary movement and meets the class policy. Extremely loose fabric and clothing that needs repeated adjustment make that harder. “Fitted” should describe how the garment works on you, rather than become a challenge to buy the smallest size available.

Read the maker’s size chart and care label before ordering. Check the return conditions before wearing or washing a new item, particularly if you are unsure about the size. If you are between sizes, ask the seller how that product is intended to fit instead of treating one brand’s label as a universal BJJ measurement.

Inspect the loan or owned kit for damage before class. Point out a tear, a failing seam, or a troublesome fastening to the coach. The IBJJF page also excludes dirty, wet, torn, or otherwise unsuitable gis from its competition specifications, but you do not need an upcoming tournament to ask whether damaged clothing should be used.

Buy only for a confirmed requirement. An academy may specify a uniform, accept suitable clothing you already own, or provide equipment within an introductory course. Our training-cost guide separates required purchases from optional ones. Confirming a loan first leaves more money for the thing you were trying to buy in the first place: a class.

Keep the changing-area problem small

Ask where to change and where your bag belongs. Wear footwear to reach the mat and for trips through the building, then follow the academy’s rules about removing it for training. Do not assume the entrance, toilets, and mat are one barefoot area.

A clean change of clothes and a separate place for used kit make the trip home easier. Pack a towel if you will shower, or confirm whether the academy supplies one. A school’s facilities can change what you need to carry; another visitor’s packing list cannot establish what is available that evening.

Keep jewelry, hard accessories, and loose possessions in your bag instead of setting them at the mat edge. If a required item is missing, tell the coach before the exercise starts. A borrowed spare or permission to observe may be possible, but it is the academy’s decision rather than a promise this guide can make.

Plan the laundry before the next session

Bring clean clothing to each session. Bellingham’s policy specifically asks students to wash the gi and belt after every class. Check how your academy handles a loan, and follow the care instructions for the items you own. A belt belongs in the clothing plan too.

The CDC’s athlete guidance recommends laundering training clothing after use, drying it completely, and following the clothing label’s washing and drying instructions. Keep this practical: know when your kit will be washed and ready again.

Read the label before choosing a wash setting. Do not use a very hot wash as a universal solution or assume every gi and stretch garment has the same care requirements. If the label is unclear, ask the maker. The clothing needs to be clean and usable after laundering, not merely smaller.

Take used kit out of the bag when you get home and keep it separate from clean clothes. If one set cannot be ready for the next class, adjust the laundry arrangement or discuss another approved set. That may eventually justify a second purchase. It does not create a requirement to buy two gis before your first trial.

Get one clear answer, then pack

Before the visit, put the essentials of the clothing question into one message: the booked format, what you already own, and what you hope to borrow. Ask the academy to confirm the acceptable combination, any charge, and when to collect a loan. A reply about that exact class is more useful than an online list of everything a grappler might eventually own.

If the format is still unknown, start there. If a loan has not been confirmed, leave it marked unconfirmed rather than packing as though it exists. If your own kit has been approved, bring that kit clean and ready; you do not need to keep searching for a more impressive outfit.

Use the kit planner for the question you still need answered. For the rest of the visit, the beginner guide covers class structure, tapping, and choosing a workable routine. The clothing decision is finished when the academy has told you what it accepts and you can bring it. You can close the shopping tabs now.

• Confirm the class format and its trial-clothing policy.
• Confirm any loan, including size, belt, collection, return, and possible charge.
• Check the approved clothes for fit, pockets, fasteners, and damage.
• Bring them clean, with a change of clothes and off-mat footwear as needed.
