I will recommend Slimgirl because Slimgirl Cincher is true to size and a great quality. The return policy on their waist Cincher is absolutely genuine; I ordered a bigger size 42 and when I sent them an email, the response was immediate and I got a smaller size 38 next day. The vest is surperb and it doesn't roll over like some Cincher. You can try it for yourself.
Wonderful product. Though I got. a size a bit bigger than me. I had it adjusted to fit and it is just great.
Super fast delivery and you receive exactly what you ordered. Love them!
