Plus-size waist trainer guide: size, length and hold

Choose a plus-size waist trainer by your natural waist measurement, not your dress size, using the chart for that exact trainer. Our trainers go up to 3XL, which fits a natural waist up to 44 inches in 8" and 10" (43 inches in the 12" Long). Pick your torso length separately, and start on the loosest row of hooks.

We'd rather be upfront about range than sell you a trainer that pinches. If you measure above the largest size on the chart for the trainer you want, it isn't made for you yet, and our fit team will tell you the same if you ask us. Everything below works the same at any size.

What sizes do our waist trainers come in?

Each line has its own chart, and the 12" length uses a different chart from the 8" and 10". So the largest waist a 3XL fits depends on the trainer.

The full charts for every line are in our waist trainer size chart. The Invisible Zip & Clip runs small, so it's the one to double-check before you order.

Measure your natural waist, not your dress size

Dress sizes vary so much between brands that they can't tell you a trainer size. A 2XL dress and a 2XL trainer often aren't the same body. Measure instead:

1. Use a soft tape measure over bare skin or a thin top.
2. Find your natural waist, right above your belly button. That's where the chart is measured, whatever your shape.
3. Stand relaxed and breathe out normally. Don't suck in or pull the tape tight.
4. Keep the tape level all the way around. A mirror helps you check the back.
5. Measure two or three times and use the number that comes up most.

Between two sizes? Go up one for your first trainer and down one if you've worn one before. The full method, with photos, is in how to measure for a waist trainer.

Which torso length?

Torso length has nothing to do with clothing size. Plenty of plus-size women have a short torso, and a trainer that's too tall is the most common reason a trainer rolls at the bottom or digs in under the bust. Measure from the bottom of your ribs to the top of your hip bone. Under 8.5 inches: 8". 8.5 to 10.5: 10". Over 10.5: 12".

If your trainer folds at the hips when you sit, try a shorter length before a bigger size. Why waist trainers roll up explains how to tell the two apart, and the torso length guide shows each step.

How much hold do you want?

Hold is personal. Start with what you'll actually wear for a few hours, not the firmest trainer we make.

For a first trainer, Active Sculpt is the easiest to get used to because it moves with you. If you'll mostly wear it under clothes, Daily Sculpt is our firmest everyday latex and lies flat under fitted outfits.

Want coverage up the back?

A standard trainer stops at your waist. Hide The Back Fat is a 12" trainer that reaches up toward the bra line, so the back of a fitted top lies smooth. It comes in latex or a latex-free version. Because it's 12" tall, it suits a medium or long torso best.

How to keep it comfortable

• Wear a thin tank underneath. It keeps latex off your skin and stops the hook strip from catching.
• Start on the loosest row, for an hour or two at a time, and add time only when it feels easy.
• Do the sit test. Sit down, lean forward, take a full breath. If an edge digs in, it's usually length. If you can't breathe fully, it's too tight.
• Skin folding over the top or bottom edge usually means the trainer is too tall or too small for you, not that you need to tighten it.
• Take it off right away if you feel pain, numbness, tingling or shortness of breath. Cleveland Clinic notes that heavy compression around the ribs can make breathing harder, so a full breath is the line we never cross.

The first few closes take effort on any new latex trainer. One customer put it simply:

“So glad I purchased this waist cincher. At first it was difficult to get on but it does stretch a little, so don't give up. Great back support. So glad I got one”

Another, Kesha R., wrote about her Neoprene trainer: "I ordered a large and it was perfect covers whole stomach and more comfortable than I expected!" More on the right feel in how tight a waist trainer should be.
