I absolutely love OKWISHING and everything I've ordered. The quality is good and the price was affordable. The pillows and comforter has to be stuffed but still worth it.

My teenage daughter needed a tube top for her first tattoo. It worked out awesome and was a great deal. She also got a strapless bra that fits overall great. She is Medium build and 5 ft. 3 inches. We received the mercy even before expected, so it was perfect timing being that she wanted the tube top for the tattoo.
