This is called a lace extender. You can wear it by itself or under a T-shirt or under a dress to totally change the look of your outfit. They are stretchy in the body (most people go down a size) These are cute with a kimono and boots or wedges. Can also be used as a swimsuit cover up. I have S-2X and the color choices are black, white and black with Leopard.
These have adjustable straps. You can also take it off of your shoulders and tuck it under your bra to add length or tuck it in your undies to get the length just right. If you want to wear it--you can make it work:)
