Clips attach this fabric panel to the bra straps. While ads claim that the panel may be adjusted higher or lower to control coverage, in reality the panel tends to slide downward to rest on the tops of the bra cups. Another drawback is that the fabric is thin like a slip, so lighter colors are semi-translucent. This product is stocked by many online and in-store retailers.
