I can’t stand TS’s. I have never been able to find a size that fits me, and they seem to pouch/pooch/buckle in all the wrong places, and pull too tight in others. So not flattering. I recently tried the new FITS Megan breech which is their new H/J line (finally!) and measured in between sizes there as well. I originally went with the L, but it did like the TS did - the pooch/pull/tight in all the wrong places, but still managed to feel really good. So I exchanged them for the mediums, and when I got them and opened the box I thought “eeeeps” never gonna fit - they looked too small. To my surprise (and delight!!!) they fit like a glove, and looked like a million bucks!
I think the difference is the materials they use. They have some power-stretch something in the stomach area and the material overall is just super comfy without being too tight, while holding in all the areas you want held in. It’s like built in Spanx or something haha! Needless to say, I’ve now abandoned all efforts of ever fitting into TS, and am a lover of FITS! I’d seen their stuff before (I event as well) but while their FS breeches are nice, I mostly show H/J so they didn’t help me. I can’t tell you how thrilled I am with their new Megan breech!
