From a recommendation on here a good couple of years ago I bought some Thunderpants (hipster style) which I absolutely loved - I have a curvy, round bum and I've always struggled with getting knickers that stay in place. I like them to curve underneath the butt cheeks rather than skimming up/across - I like to feel that I'm contained! This means that they also needs to have a wider than average gusset.
The Thunderpants were great - fitted perfectly, didn't ride up at all so didn't budge all day, and were nice thick organic cotton. However they are expensive - around £14 each at the moment - and I need a good few pairs, plus they don't have a UK arm anymore so have to ship them from NZ.
The few pairs I had have all now fallen apart from over use...does anyone have any suggestions? I've tried so many pairs from M&S, Gap, Sloggi etc and they are all too skimpy and not wide enough. And I literally can't bear to wear them if they ride up as it irritates me so much!
