This is great slip design. Bali has thought of almost every detail: an easy-to-hook/unhook gusset that keeps the slip from riding up, just enough pressure to shape without making your body look like a mono-slug, and material that behaves nicely under a variety of fabrics. The cups fit exactly according to size. All in all, it's a faboo deal versus pricier under-performing competitors. Why only four stars? The bra straps are a bit narrow for C cup and up; adding a 1/4" to strap width would help. And Bali doesn't offer all the sizes it should, see Tip 2 below.

Tip 1: The neckline is fairly modest, so this won't work with a plunge neckline or anything cut low into the corners. Tip 2: If you're a 32D, which Bali doesn't have, opt for the 34D -- the band still provides decent snugness.
