Part 3. Exercise
I earlier wrote that I did not receive these as ordered, but the seller immediately contacted me and sent this item quickly. Great service! The look is fun and sexy -- these are cut REALLY low. They will probably reveal a bit of butt cleavage, but my girlfriend and I really like the different look and feel of these quality panties. I knocked off one star because they run a bit small; order a size up if in doubt.
Answer:
Positive
