Worth it!

At first I was not happy but realized I had the wrong size! I love the thong underwear and the no wire bras and triangle bra. LOVE the way they fit and LOVE the way they look and feel. As much as I usually save nice things like this, I’ve decided to use them as my everyday bras and undies bc they are that heavenly and I’m worth it!
