Review: 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!!
Review: 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!

### ⭐ Repeat purchase but smaller fit !!!
*by S***E on 4 May 2026*

These were a repeat buy (from 2 pairs previously purchased ) so I bought 4 pairs more in black and cream and after opening up the packages and packing them for my holiday … Same size same make … but they felt a lot smaller than the original pairs I bought ! Uncomfortably too small sadly so I’m not sure if I’m able to get a refund for the 4 pairs tried on all very uncomfortably !! Sorry but true !
