Red Dress/Beach Cover Up

I purchased several of these dresses for a trip to Mexico. They are super comfortable to toss on after a day at the pool/beach. They can be worn with or without the sleeves. They are the high/low style with the back being a little longer. The black one has no size tags but is similar size to the red which is a size small. The red does feel a little bigger personally. They do have a large amount of stretch to them.
