Mummy tummy heaven!
Arrived today and I’m surprised at how effective they are! I’m a UK size 10 (US 6) and have a bit of a mummy tummy, so went for the 36. I’ve tried other shapewear and it always seems to concentrate on the upper part of the tummy, pushing everything down. But this targets the lower tummy perfectly! No muffin top. And the thong aspect really boosts my (usually not that impressive) bum. Perfect for leggings, my hubby’s not been able to keep his hands off me all afternoon! Defo buying more!

Can't return them
Poor quality. Feel really let down by this product it's nowhere near as high as shown in the pictures and more like a pair of bikini briefs. Brought two to try as the sizing is confusing. Didn't even try them on they were tiny but the worst thing is they are not elligable for returns. Please don't but these.

Not like previous Spanx
Comfortable but not like previous Spanx where i’ve literally needed a shoe horn to get them on, fabric softer & defo not tighter.

Good
Good product, do their job but don't expect them to hold as much as other spanx. They give you just that little help, exactly what I needed.

Bridesmaid dress undergarment
Purchased for bridesmaid dresss undergarment to keep me feeling confident all day. Product as described and true to size. Perfect for open back dress and keeping a smooth lower belly.

Top rolls down
Not a good fit on me. I’m petite size 8-10 and wanted to flatten my mum-tum. These did but created a mini muffin at the top, cutting me off just above the belly button. And when I sat down the top rolled down. Not streamline for me. Attractive looking though, as shapewear pants go. Just not for me. I found the Werena pair far better, they come higher and don’t roll. (And much cheaper!)

Looked minuscule but stretched!
I LOVE them! I ordered a proper rib-to-thigh one but I’ve never worn it. It’s such a struggle just at home and to wear it out I feel would be a nightmare - trying to get out of it in time for a wee! These however are great. I gained weight in lockdown and my hips are out of control. These just pull them in and smooth over my tummy to make a tight dress/ skirt look better. One thing I’ve noticed is that if I sit down in them too long they make my buttcrack sore.. but that could just be me lol! Am gonna get some more. Am a uk10 with uk12 hips/ bum and I ordered a small. They stretch!!

These do not give a super hold/compression but they’re sexy to wear when your drains are out and you’re wearing a waist compression after a tummy tuck

I had two different wedding dresses, both form fitting but different types of fabrics but these were PERFECT for both and very comfortable!

I’m 5’9 190 size 14. I was looking for something to wear under my uniform. These are great. I got a size XL and they fit perfect. Just enough to smooth a little bit of my belly without making me feel like I’m wearing shapewear. Good quality too.

very soft and comfortable. Great job at holding the lower belly in. Love the fit!
