There are two different bras listed under this product. When you look at the pictures, please note that some have a strap closure in the front.
The strap can be unhooked and they can be crossed in the back. The other bra shown has no strap closure in the front and therefore cannot be criss-crossed in the back.
Other than that the style seems to be the same, but the material is different. The bra with the strap closure in the front is made from a heavier material and the other from a much lighter material. With the summer coming,
I ordered not realizing it was a different bra (my old one has the strap closure in the front) then I bought locally. I will give the lighter one a try even though the cup a little too big for me. Unfortunately, there are limited sizes available for the bras shown.
