I absolutely love these panties! They are some of the most comfortable panties Ive ever worn. They stay in place and don't ride up at all. They are a stretchy type material & hug your curves. Ive had these about 7-8 months now and they are still in very good condition. At the time of purchase I weighed about 135-140 (53) and ordered a medium and they fit great. Since then Ive lost down to 117. I can actually still wear them but when I get ready to order some more Ill drop down to the smalls. But theres a lot of play in the size scale because of the way they hug your body. Dont hesitate to order these...youll love them. Theyre just as great, if not better than other panties Ive paid $12-15 a pair for.
