This set is soft and cozy. Both pieces are white with navy stripes. Both pieces have been worn one time. Of course they can be worn together or separately. The tank is ribbed. It is a Chico's size 1 (equivalent to M 10-12 in other brands). The cardigan is a Chico's size 1P (petite). Both pieces are like T-shirt knit but softer and with a bit more structure and plenty of stretch. (I apologize for the wrinkles! This has been in storage.)
