The Bra Clips are as described on the product description page. This came as a set of 4 plastic clips. There is black, beige, white and clear clips. They are very easy to transform a regular bra into a racer back bra. They work very well. I noticed a lot of the fashions this year had the racer backs on dresses and shirts. Undergarments can be expensive if you have to have different ones for different styles of shirts. I haven’t had that chance to actually wear these with any shirts because I have been avoiding that style. I can now purchase a few of the fashions and not have to worry about my straps showing. I guess I must be a little old fashioned, because I always see straps showing and think it looks cheap. I received these free in exchange for my review.
