Starting something new can feel a little intimidating, and walking into your very first Jiu Jitsu class is no different. Whether you’ve been binge-watching UFC fights, got inspired by a friend who trains, or just want a new way to get fit and build confidence, stepping onto the mats for the first time is an exciting moment. But there’s one thing almost everyone asks before they go: What do I wear to class?

It might seem like a small detail, but the clothes you choose for training can make a huge difference in your comfort, safety, and overall experience. Jiu Jitsu isn’t like going for a run where you can just throw on any old t-shirt and shorts. Because it’s a grappling-based martial art, what you wear directly affects not only your performance but also your partner’s ability to train with you.

Let’s break it down in a clear, friendly way so you know exactly what to wear, what to avoid, and how to feel confident walking into your first Brazilian Jiu Jitsu (BJJ) class.

The Basics: Understanding Gi and No-Gi Jiu Jitsu

Before we talk about clothing, it helps to understand that there are two main styles of BJJ training: Gi and No-Gi.

• Gi Jiu Jitsu uses a traditional kimono-style uniform, usually made from thick cotton. It includes a jacket, pants, and a belt that indicates your rank. The fabric is durable because opponents grab and grip it throughout training.

• No-Gi Jiu Jitsu is practiced without the traditional uniform. Instead, students typically wear rash guards (tight-fitting, stretchy tops) and grappling shorts or spats (leggings). No-Gi training focuses more on body grips rather than fabric grips.

Your first class may fall into either category, depending on the gym. If you’re unsure, reach out to the gym beforehand and ask, “Is this a Gi or No-Gi class?” That simple question will save you from showing up unprepared.

What to Wear if It’s a Gi Class

If your first Jiu Jitsu experience is in a Gi class, don’t panic if you don’t own a Gi yet. Many gyms, like PirateBJJ offers Brazilian Jiu Jitsu Gym, will let beginners borrow or rent one for their trial class. Still, it’s good to know what’s expected.

The Gi Itself

A Jiu Jitsu Gi isn’t the same as the karate or taekwondo uniforms you may have seen. It’s thicker, sturdier, and built to withstand tugging and pulling. A typical beginner’s Gi includes:

• Jacket (kimono top)

• Pants

• Belt (usually white when you’re starting out)

If the gym provides one, just wear it as instructed. If you buy your own, go for a beginner-friendly Gi in a standard color like white, blue, or black.

Under the Gi

Always wear something under your Gi. For men, that usually means athletic underwear and a t-shirt or rash guard under the jacket. For women, a sports bra and compression top or rash guard under the jacket is standard. This extra layer helps with hygiene and comfort since you’ll be sweating and moving constantly.

What to Wear if It’s a No-Gi Class

No-Gi training doesn’t require a uniform, but it does require specific types of clothing. The focus is on stretchy, fitted, and durable materials that won’t get caught or ripped.

Rash Guard

A rash guard is the most common top worn in No-Gi. It’s a tight, compression-style shirt that protects your skin, keeps sweat from soaking your partner, and helps prevent mat burns. If you don’t have one yet, a snug athletic shirt made from moisture-wicking fabric will work for your first class.

Shorts or Spats

For bottoms, you’ll want grappling shorts (no zippers or pockets) or spats (leggings). Regular basketball or running shorts with pockets aren’t a good idea because fingers and toes can get caught, leading to injuries. If you’re starting out and don’t own grappling shorts, opt for snug gym shorts without zippers or anything loose that could snag.

Footwear

Jiu Jitsu is always practiced barefoot on the mats. You’ll wear flip-flops or slides to walk from the locker room to the training area, but once you step onto the mat, shoes come off. Never wear street shoes on the mats—it’s a major hygiene rule in every gym.

What Not to Wear to Your First Jiu Jitsu Class

Knowing what to avoid is just as important as knowing what works. Here are some things you’ll definitely want to leave at home:

1. Loose T-Shirts and Baggy Shorts
   They’ll get tangled, stretched, and pulled. Plus, they don’t offer much skin protection.

2. Clothing with Zippers or Buttons
   Anything with hard edges can scratch or cut your training partners.

3. Jewelry and Accessories
   Rings, earrings, necklaces, and watches should all be removed before training. They’re unsafe for both you and your partner.

4. Shoes on the Mat
   This one’s worth repeating: never step on the mats with your outdoor shoes.

5. Anything You Don’t Want Ruined
   Training is sweaty, physical, and rough on clothes. Don’t wear your favorite shirt or expensive gym gear unless it’s designed for grappling.

Hygiene: The Unspoken Dress Code

What you wear is important, but how you wear it matters just as much. BJJ is a close-contact sport, so hygiene is a huge part of being a good training partner.

• Wash your Gi or rash guard after every class. Don’t ever wear unwashed gear—it’s uncomfortable for you and unpleasant for others.

• Trim your nails (hands and feet) to avoid scratches.

• Tie back long hair to keep it from getting in the way.

• Wear deodorant but skip heavy perfumes.

Being clean and considerate makes everyone’s experience better and shows respect for your teammates.

Tips for Feeling Comfortable and Confident

That first class can feel a little nerve-wracking, but the right gear helps you settle in. Here are a few extra tips to make sure you’re ready:

1. Ask if you can borrow gear. Many gyms loan Gis or have extra rash guards for beginners.

2. Bring water and a towel. You’ll sweat more than you expect.

3. Arrive a few minutes early. That way, you can introduce yourself, get changed, and not feel rushed.

4. Don’t overthink it. Your training partners know you’re new, and they’re usually happy to help you adjust.

Common Beginner Questions About Jiu Jitsu Clothing

Q: Can I just wear my regular gym clothes?
Sort of. If they’re tight-fitting and don’t have zippers or pockets, it’s fine for your first class. But long-term, it’s better to invest in proper gear.

Q: Do I need to buy a Gi right away?
Not usually. Most gyms encourage you to try a few classes before buying one.

Q: What about shoes designed for wrestling?
Those are for wrestling mats, not Jiu Jitsu. BJJ is almost always barefoot.

Q: Can I wear makeup or lotions?
It’s best to skip both. Makeup can smear, and lotions make you slippery, which isn’t ideal for grappling.

Building Your Training Wardrobe

Once you know you’re committed to Jiu Jitsu, it’s worth building a small wardrobe of training gear. A beginner’s setup usually looks like this:

• 1–2 Gis (if you train Gi)

• 2–3 rash guards

• 2–3 pairs of grappling shorts or spats

• Flip-flops or slides for off-mat use

• A gym bag for carrying everything

Over time, you’ll figure out what styles and brands you like best. Some people prefer lightweight Gis, while others like the heavy-duty ones. Some love flashy rash guards, while others keep it simple. It’s all about personal preference once you’ve got the basics covered.

Why Dressing Right Matters More Than You Think

It’s not just about looking the part. The right clothing helps you move better, keeps you safe, and shows respect for your training partners. In Jiu Jitsu, your partner’s experience is just as important as your own. If your clothes are uncomfortable, unsafe, or unhygienic, it affects everyone on the mat.

When you dress appropriately, you can focus on learning techniques instead of worrying about adjusting your shirt or tugging at uncomfortable pants. You’ll feel more confident, and your partners will appreciate it too.

Final Thoughts

Walking into your first Jiu Jitsu class is a big step, but don’t let clothing stress you out. Whether it’s a Gi class or No-Gi, the main goal is to wear something safe, clean, and comfortable. Stick to fitted athletic gear, avoid anything with zippers or pockets, and remember the golden rule of hygiene.
