*by S***S on 22 July 2024*

I bought to wear under a dress I was wearing to a wedding! They are so comfortable and feel the control on the old belly area, just the right amount of support without feeling too tight. Mine were a bargain price of £10.00. And size medium I am 52 and a size 10.

### ⭐⭐⭐⭐⭐ Nice fabric.
*by P***Y on 5 May 2023*

Good fit, nice and smooth.

### ⭐ Size not accurate
*by A***R on 20 October 2025*

The size guide is not accurate. According to it I am size XS . In reality they are so small they can't fit on my cat. You can not return or replace the item which is a shame.
