I like the dress but was very disappointed that it came torn right on the front so it can't even be hidden. Edit: I would like to add the I've bought several dresses from this company and this was the only one I had an issue with. They were very polite and I would recommend buying from them.

I purchased them for my husband because he was complaining of heel pain when exercises and want not too tight socks around the ankle. They came earlier than what they state. They are made of nice material that make soft compression on on your heels and not too tight. They mentioned it should be hand wash but I washed them many many time in gentle cycle and yep they still doing the same work. I just wish if they could make it with other different colors to match out fit. I made another purchase but for me this time. I like to wear them when I work at home as well at the park when I go to play with my kids
