Figuring out what to wear to your first BJJ class trips up almost every beginner. Unlike a regular gym, the mat has rules: zippers scratch training partners, pockets trap fingers, and shoes never touch the tatami. Show up in the wrong outfit and you may spend your first hour watching from the sidelines. The good news is that you almost certainly already own enough to train, and most Texas gyms will lend you a gi for free on day one.
In this guide, we break down the full dress code for both gi and no-gi classes, what to leave at home, and the hygiene habits that make you a training partner people want to roll with. Whether you’re stepping onto the mat in Houston, Austin, or Dallas, the BJJ dress code is the same — and simpler than you think. By the end, you’ll know exactly what to pack for day one.
What to Wear to Your First BJJ Class: The Short Answer
Call the gym before you go — seriously. Most BJJ gyms in Texas keep clean loaner gis in beginner sizes specifically for first-timers, and many will let you try a class in a t-shirt and athletic shorts while you decide. Here is the quick breakdown:
- Gi class: a gi (jacket plus pants) with a belt, worn over a rash guard or snug t-shirt. Borrow one from the gym if you can.
- No-gi class: a snug rash guard or athletic shirt plus grappling shorts, board shorts, or leggings — no pockets, no zippers, no loose drawstrings.
- Feet: barefoot on the mat. Bring flip-flops or slides for anywhere off the mat, especially the bathroom.
- Hair: a firm elastic tie with no metal parts; long hair does better with two ties.
That is genuinely it. You do not need to buy anything before your first class, and any gym that pressures you into a $200 gi purchase on day one is waving a red flag. Train with what the gym lends you, then invest once you know you love it.
BJJ Gi Basics: What Goes Under, Over, and Around
The gi — called a kimono in Brazil — is the traditional uniform of Brazilian Jiu-Jitsu: a heavy cotton jacket, matching pants, and a cloth belt that holds it closed. For your first class, cleanliness matters more than color; white, blue, and black are the standard choices. Under the gi, most people wear a rash guard or a tight synthetic t-shirt, and women typically pair a sports bra with a rash guard. Loose cotton shirts bunch up and get stretched out within minutes of grappling.
If you decide to keep training, a starter gi runs roughly $60–$120 and lasts a year or more of regular use, and your gym will give you your first white belt — you never buy your first belt.

No-Gi Attire: Rash Guards, Shorts, and Spats
No-gi is Brazilian Jiu-Jitsu without the uniform, and the dress code is even simpler. The core rule is that everything fits snug and nothing can catch a finger:
- Rash guard: snug and synthetic, short- or long-sleeved. It wicks sweat and survives grabbing far better than cotton.
- Shorts: grappling or board shorts with an internal drawstring — no pockets, zippers, or exposed metal.
- Spats or leggings: optional compression leggings. Standard for women and common for everyone in colder gyms.
If you already own gear for running or the weight room, you are most of the way there. An old synthetic athletic shirt beats a cotton t-shirt every single time.
What Not to Wear to Your First BJJ Class
Some items do not just look out of place — they are genuinely dangerous in a sport where fingers, toes, and faces get caught in everything. Leave these at home:
- Jewelry of any kind: rings, watches, earrings, and necklaces scratch partners and rip out under pressure.
- Pockets, zippers, or snaps: on shorts, shirts, or sports bras, they snag toes and fingers.
- Socks: bare feet grip the mat; socks slide and cause ankle injuries.
- Makeup, lotion, or fragrance: it transfers straight onto the mat — and onto every training partner on it.
- A dirty gi: a smelly uniform is the fastest way to lose training partners in any Texas gym.
Mat Hygiene: The Habits That Keep You Rolling
Brazilian Jiu-Jitsu is a close-contact sport — closer than any other martial art — so hygiene is part of the dress code. Trim your fingernails and toenails short before class, shower as soon as you can afterward, and never reuse a gi or rash guard without washing it. Wear your flip-flops from the changing room to the mat edge, and never walk barefoot on a bathroom floor. Gyms mop their mats nightly, but skin infections such as ringworm spread fast in combat sports, and clean gear is your first line of defense.
Ready for Your First Class?
Here is the recap: call ahead, borrow a gi or bring a rash guard and pocketless shorts, trim your nails, and pack flip-flops. That is everything you need to not just survive but genuinely enjoy your first BJJ class — the hardest part is walking through the door. Ready to find a gym?

Frequently Asked Questions
Q: Do I need to buy a gi before my first BJJ class?
A: No. Most gyms lend beginners a clean loaner gi for free, and many let first-timers train in a t-shirt and athletic shorts. Wait until you have trained a few times before spending $60–$120 on your own gi.
Q: Can I wear a regular t-shirt and shorts to a BJJ class?
A: For a no-gi class, yes — as long as the shorts have no pockets or zippers and the shirt fits reasonably snug. For a gi class you will need to borrow or buy a gi.
Q: Do you wear shoes or socks in Brazilian Jiu-Jitsu?
A: No. BJJ is trained barefoot for grip and safety. Bring sandals or flip-flops to wear off the mat, especially in the changing room and bathroom.
