Turning up to your first class and realising you have no idea what to wear is more common than you think. If you’ve been asking what should I wear to BJJ, the good news is you do not need a wardrobe overhaul or a bag full of expensive gear. You just need the right basics for the class you’re attending, a clean set of clothes, and a little common sense.
Brazilian Jiu-Jitsu is close-contact training. That means what you wear affects your comfort, your safety, and your training partners’ experience too. The right kit helps you move properly, stay covered during scrambles, and train without constantly adjusting your clothes.
What should I wear to BJJ for your first class?
The first thing to check is whether your class is gi or no gi. That changes everything.
If it’s a gi class, you’ll usually wear a BJJ gi, which includes a jacket, pants and belt. Some academies have loaner uniforms for trial classes, and some will let beginners start in a plain T-shirt and athletic shorts until they decide to continue. If you’re not sure, ask before class rather than guessing.
If it’s a no gi class, you do not wear the traditional kimono. You’ll usually want a fitted rash guard or athletic shirt and shorts designed for movement. Ideally, those shorts should not have zips, buttons or hard plastic parts that can scratch your training partners.
For both styles, your gear should be clean, fitted well enough to stay in place, and comfortable enough to let you squat, bridge, shrimp and move freely. Baggy clothes can get grabbed, twisted or bunched up. Clothes that are too tight can restrict movement and become distracting fast.
What to wear to gi BJJ
A gi class has a more traditional uniform standard, but beginners do not need to overcomplicate it.
A proper BJJ gi is the best option because it is built for grappling. The jacket is reinforced in key areas, the pants are tougher than standard martial arts pants, and the cut is made for movement on the ground. A judo gi can work in some cases, but it is usually heavier and fits differently. A karate uniform is generally too light for regular BJJ training.
Under your gi, most men wear compression shorts or regular athletic underwear, and many choose to wear a rash guard under the jacket for comfort. Many women wear a sports bra and rash guard or fitted compression top under the gi. The goal is simple – stay comfortable, stay covered, and avoid clothing that shifts around once training starts.
Your belt matters less on day one than your overall presentation. If the academy lends you a gi, they may also lend you a belt. If you already have a gi but no BJJ rank, wear a white belt unless the academy tells you otherwise.
Fit matters more than many beginners expect. Sleeves that are too long, pants that drag under your heel, or a jacket that barely closes will all become annoying very quickly. A little room is fine. Swimming in fabric is not.
What to wear to no gi BJJ
No gi is simpler, but the details still matter.
A rash guard is the gold standard because it stays in place, handles sweat well, and reduces friction on your skin. If you do not own one yet, a fitted athletic shirt is usually fine for a trial class. Avoid loose cotton shirts if you can. Once they get sweaty, they stretch, twist and become uncomfortable.
For your lower half, wear grappling shorts or athletic shorts without pockets, zips or metal parts. Those features can catch fingers and toes or scrape skin during scrambles. Some students wear compression shorts or spats under their shorts for extra coverage. That is a smart option, especially if you are new and want to feel secure while moving.
Women often prefer a rash guard with leggings or shorts, depending on comfort and academy rules. Men usually wear shorts over compression wear. In either case, choose clothing that stays put during fast movement.
If you’re weighing up style versus practicality, practicality wins every time. No gi training is fast, sweaty and movement-heavy. If you have to think about your clothes every round, they are the wrong clothes.
What not to wear to BJJ
This is where beginners can avoid the most common mistakes.
Do not wear shorts with zips, buttons or bulky pockets. Do not wear jewellery, including rings, necklaces, bracelets or dangling earrings. Do not train in clothing with sharp or hard details. And do not wear anything so loose that it can ride up, get tangled or leave you adjusting it every few seconds.
Also, avoid training in a singlet by itself unless the academy specifically allows it. In grappling, coverage matters. A fitted shirt or rash guard is usually the better call.
Shoes do not go on the mats. You’ll usually wear thongs or slides to the edge of the mat, then step on barefoot. That helps keep the training area clean. If you’ve come from outside, do not walk straight onto the mat in the same footwear you wore through the car park.
Comfort, hygiene and safety matter as much as the uniform
A clean gi or clean no gi gear is not optional. It is part of good training etiquette.
BJJ is hands-on and close-range. If your gear smells, hasn’t been washed, or has been sitting damp in your bag, everyone around you will notice. Freshly washed gear, trimmed fingernails and toenails, and basic personal hygiene all matter. That is not about being overly formal. It is about respect for your training partners and keeping the room safe and professional.
Long hair should be tied back securely. If you wear make-up, keep it minimal because training gets sweaty quickly. If you have any cuts or scrapes, cover them properly before class.
There is also a practical side to quality gear. Better fabrics tend to hold up longer, fit better and stay in place. But beginners do not need to buy the most expensive setup on the market. Start with what meets the standard, then upgrade once you know how often you’ll train and whether you prefer gi, no gi, or both.
What beginners usually need to buy first
If you’re starting out, buy for your current routine, not your future fantasy.
If your academy schedule is mostly gi classes, one well-fitting gi is enough to begin with, though two becomes more practical once you train multiple times a week. If you’re starting with no gi, a couple of rash guards and two pairs of proper grappling shorts will usually cover you. You can build from there.
Some people want every piece of gear before they’ve completed one session. Others turn up underprepared and hope for the best. The smart middle ground is to get what you need for the classes you’ll actually attend and make sure it is clean, safe and comfortable.
At a beginner-friendly academy, the staff should make this easy. They’ll tell you what the dress standard is, what can be borrowed, and what you should buy first. That support matters, especially if your first goal is simply getting on the mat without feeling awkward.
Does it change for kids, teens and women?
The basics stay the same, but fit and comfort become even more important.
For kids and teens, parents should focus on durable gear that allows movement and can handle regular washing. There is no benefit in buying oversized gear “to grow into” if it makes training harder now. A better fit is safer and more comfortable.
For women, the best setup often comes down to personal preference within the academy’s dress standards. A well-fitted rash guard, supportive sports bra and secure leggings or shorts are usually a strong combination for no gi. For gi, many women add a rash guard under the jacket for comfort and coverage. The key is to choose gear that lets you train confidently without distraction.
The best answer is the simple one
If you’re still wondering what should I wear to BJJ, keep it straightforward. Wear the correct gear for gi or no gi, make sure it is clean, avoid anything that could scratch or snag, and choose fit over fashion. That is enough to get started well.
At a quality academy, nobody expects beginners to know everything on day one. They do expect you to arrive ready to learn, ready to train safely, and ready to be part of the team. Get those things right, and your clothing stops being a worry and starts doing what it should – helping you focus on getting better every day.
