Comfortable and cute

I don't usually get thongs, but I really liked this sporty/sexy style. I decided to give it a try and I'm glad I did! They are perfect under my tight fitting pants, and the wide waistband is super comfortable to wear either low, or with the sides pulled up as a high-cut.

Out with the old, in with the Negative

This is my 4th or 5th purchase from Negative. I've lost count. I have completely replaced my old lingerie wardrobe with Negative. This line of under garments are my favorite. There's no going back for me.
