The 10 Best Waist Trainers to Buy in 2026

People have been using shapewear to enhance their silhouette for centuries. While dramatic full skirts that needed extra support to keep their shape are a fashion of the past, more and more people are returning to the idea of corsetry and waist training. Of course, Kim Kardashian probably has a lot to do with that, but more on that later.

Corsets were never an evil torture device used to oppress women, as they are sometimes said to be, (you can find a brief history on the subject later in this article) and they still aren’t today. Whatever your reasons for waist training, you can find information about how to do it safely in a way that helps you reach your goal.

What Is Waist Training?

Waist training occurs when you wear a tight support garment around your torso to adjust your shape and gradually change it. While Kardashian often posts pictures of herself wearing latex trainers, her famous MET Gala look was most likely achieved by wearing a much more structured, steel-boned corset device.

Wearing waist trainers can give your body a more dramatic hourglass look. Over time they can help shape the way your body carries abdominal fat (and it’s normal for everyone to carry some abdominal fat). While waist training is mainly done by women, anyone can enjoy using silhouette smoothing cinchers.

Types of Waist Trainers

There are a few categories that most waist trainers fall into. This determines the style, how restrictive it is, and when it should be worn.

Athletic Trainers

These belts tend to be made from stretchy materials like neoprene, latex, or other stretchy poly-fiber fabrics. Many are unboned (more on that in a moment) and are meant to give extra support mainly while you work out. They warm your middle up to increase perspiration and give some spinal protection (like a lifting belt) while you’re weightlifting.

Underbust Trainers

Many waist trainers are worn under the bust to focus on the waist and make sizing easier. Waist size does not always directly relate to our bust size, after all. You’ll still need a bra with this style of trainer since it doesn’t provide bust support.

Overbust Trainers

These are dramatic waist trainers that are well suited to wearing for special occasions like weddings and formal events. They come up over the breasts, making a bra optional.

Bodysuits

This style of trainer will be familiar to shapewear enthusiasts. They cover the waist, lower belly, and the butt. If you want to have all your edges smoothed out to wear under a bodycon dress, these tend to be a good choice. Without boning, they’re usually made of materials like latex.

What Is Boning?

To give extra support and improve waist reduction, some waist trainers will have steel bones. Many use lighter and more flexible spiral bones (which are thin loops of steel layered over each other) for a lighter and more comfortable fit.

Some will use thin strips of solid steel similar to the blade of a hand saw (though without the sharp teeth of course!). Others will use flexible plastic bones.

Waist trainers that are made from tight stretchy materials tend not to have boning, but rely on the fabric tension instead.

Closure Styles

There are several different ways that your waist trainer can close. It often depends on the material or style of the waist trainer.

Zipper: A modern, no-fuss style closure that is often found on latex corsets and bodysuit style trainers.

Hook and Eye: Just like a typical bra closure, many underbust waist trainers will have several rows of hook and eye closures so you can adjust how tight the garment is over time.

Lacing and Busk: Many boned underbust waist trainers will use more of a traditional corsetry style of closure. This combines adjustable lacing in the back with a hooking busk closure in the front.

Velcro: Some athletic style waist trainers wrap around the waist and are secured by Velcro. This also makes them more adjustable.

Sizing

Most companies will have their own size chart and recommendations for fitting. For waist reduction, it’s recommended to only try and reduce it about 2-4 inches. That may not seem like a lot, but the shape of the garment will give you an overall more dramatic shape, emphasizing your waist. As your body gets used to waist training, you may be able to reduce it slightly more. Be aware that tight lacing and over-wearing waist trainers can have some side effects, which we will discuss later on.

If you are very muscular, it might actually be harder to reduce your waist. The squishier you are, the easier it is to manipulate your shape. Some waist trainers will also enhance the proportions of your bust and hips by pushing extra squish from your waist in those directions.

For each product on our list, we’ll include size chart information or reduction recommendation from the manufacturer.

Now you’ve got an overview of the types of trainers available, here are some of the best waist trainers on the market. Whatever your needs, there’s hopefully an option that will work for you and help you achieve your goals.
