Why have a sleeveless sun-protective dress you ask? Well, Coolibar's Oceanside Tank Dress was designed to give you coverage options for those times when you’re in and out of the sun. Show off those toned arms when you’re inside and throw on one of our UPF 50+ wraps or shawls over the tank dress when you step out into the sun. You choose the amount of coverage when, and where, you need it most!
