My husband and I went in out of curiosity and we happened to be in the shopping center. We were greeted by two women and they made their presence known, as they kinda followed us around the store. NOT a good idea, because people kind of want their privacy when roaming an adult store, especially for guys.
We weren't going to buy anything anyway, but our curiosity got the best of us. We would recommend the store to friends, but the women there made us feel very uncomfortable.
They seem to have a variety of items, but they were very expensive. For instance, a simple "costume", such as maid or nurse costumes for women were almost $100. You can get a much better price online, even with lingerie giant, Frederick's of Hollywood.
But if you need something fast... I guess this is the only way to go in Rockville.
