These are perfect for wearing that blouse that shows just a bit too much clevage for work.  I was easily able to accomodate a 1" bra strap through the product.  It has 3 snaps so adjusting for different size bra straps is easy.  The bands used to attach the product are elastic so they even allow more stretch room.  Definitely a plus to my wardrobe without the added heat caused by layering up clothing.
