I needed to order probably two sizes smaller than I normally wear, They stretch too much from my waist to the stride (crotch). I think the quality of the material used was great. However in the stride it is much too wide for comfort. Too expensive for this experience of no return.
Firm? No way. Nice underwear? Sure. But certainly not a "firm" shaping brief. I kept them because I needed two new pairs of panties, but it's back to the search for a proper shaping undergarment. I'm soooo glad I got these at 40% off. At any rate, they are a lot less per PANTY then the [@] panties that I usually buy. But I like [@] better.
If you are looking for control, these are a good option. I personally have a hard time wearing something this constricting all day. However, they are great for special occasions/clingy clothing, where control is necessary.
