What I Wish I'd Known Before Buying 3D Leggings

You've probably seen them everywhere: the 3D leggings that promise to lift, smooth and sculpt. Maybe you're about to buy a pair. Maybe you already did, and they didn't live up to the photos.

I've been on both sides. My first pair looked great for about three weeks. Then the texture faded, the waistband rolled down every time I sat, and they went see-through when I bent over.

So before buying again, I worked out what actually separates a good pair from a bad one. The CELLUTIX Triform™ is the only pair I've found that passes every check.

A 4.8/5 rating from 2,000+ reviews, buy one get one free, and a 30-day risk-free guarantee made it an easy decision. Here are the checks I now do before buying any pair.

1.Check if the texture is knitted in, or just printed on

Printed texture fades after a few washes. Once it's gone, you're left with a plain, ordinary legging.

On CELLUTIX Triform, the texture is part of the knit itself, so it still looks new after many washes.

2.Check if it lifts, holds and smooths, or only does one

Most pairs only do the texture. CELLUTIX Triform uses a Lift-Hold-Smooth System: the 3D texture smooths the look, the supportive knit holds, and the high waist lifts.

Together it feels firmer under clothes, without squeezing.

3.Sit down for ten minutes and watch the waistband

A waistband that rolls down means constant tugging. It's the first thing that made me give up on my old pair.

The high waist on CELLUTIX Triform sits above the belly button and stays there, even sitting cross-legged on the floor.

4.Do the squat test in daylight

Thin fabric goes see-through when you bend. A bright window will tell you everything in seconds.

The CELLUTIX Triform™ is dense enough to be fully squat-proof, but still breathes.

5.Check the size range and how honest the size guide is

CELLUTIX Triform comes in S to 5XL, and the size guide is honest.

My tip: if you're between sizes, size down. And if you get it wrong, CELLUTIX swaps your size for free.

6.Ask yourself: would I wear these all day?

If they're only bearable at the gym, you won't wear them.

CELLUTIX Triform is soft enough for the school run, the office and the sofa.

7.Plan for more than one pair

If you love them, you'll want to wear them daily. One on, one in the wash.

The buy one get one free offer on the CELLUTIX Triform™ makes that easy.

8.Read what real buyers say

Final Thoughts

Whether this is your first pair or you're replacing one that let you down, these checks will save you a lot of disappointment.

The CELLUTIX Triform™ is the only pair I've tried that passes all of them. With a 30-day risk-free guarantee and free size exchanges, there's really nothing to lose.
