A US designer has come up with an invention that covers up your 'butt cleavage' when wearing low-rise jeans.Kimberly Brewer has created the Backtacular Gluteal Cleft Shield, an adhesive fabric patch that's applied directly to the skin on the lower back.She came up with the idea while sporting her favourite jeans, which exposed too much of her 'gluteal cleft' whenever she sat or bent over.Made of hypo-allergenic denim and decorated with studs and rhinestones, the patches come in several colours and designs including butterflies, flowers, hearts and peace signs.The BGCS can be bought online from Ms Brewer's Kimberlily site at www.kimberlilyonline.com.
