A simple solution to stop straps from falling off your shoulders and prevent bust from straying outside your dress armholes is a nonslip rug pad. Cut product to fit inside straps and around the inside of the arm hole, pin & whipstitch. Wearing your strap gown/dress worry-free adds peace of mind and confidence. Unconventional fix? Yes, please!
Note: I sewed a bra into this low waisted (in the back) gown and clipped & sewed the bra over the bust areas that may show while moving in the dress. This extra alteration prevents bothersome mishaps. The pinning took place while the bride was wearing the bra & dress. The bra was clasped during pinning, making adjustments as needed. Once the dress was removed, the back half of the bra was cut at the side seams after being hand stitched into the dress.
