Quick answer

The fastest fix for slipping bodysuit straps is a small piece of double-sided fashion tape at the shoulder seam. For a more permanent solution, use clear bra strap holders that clip straps together at the back.

Why bodysuit straps slip more than bra straps

Bodysuits are cut for a smooth silhouette, so the straps are often thinner and set wider than a typical bra. A lace bodysuit like Cosabella's sleeveless lace bodysuit has a plunging V-neckline and a thong back, which means the straps have less fabric anchoring them in place. The stretch in lace and elastane blends can also relax over a day of wear, letting straps slide off your shoulders.

When to skip fashion tape

Fashion tape works best on smooth, non-delicate fabrics. If your bodysuit is made of fine lace or has a loose weave, the tape's adhesive can snag or leave residue. For lace bodysuits, stick to the strap holder method or the internal snap trick below.

5 ways to stop bodysuit straps from slipping

  1. Use double-sided fashion tape: Cut a 1-inch piece of double-sided fashion tape. Press it between the strap and your shoulder at the seam where the strap meets the front of the bodysuit. This creates a gentle adhesive hold that lasts hours. Test a small piece on an inner seam first to check for residue, especially on lace or delicate fabrics.
  2. Clip straps together with a bra strap holder: Take a clear or matching bra strap holder (a small plastic or metal clip). Gather both straps at the center of your back, just below the nape of your neck, and clip them together. This pulls the straps inward so they stay on your shoulders. Make sure the holder is flat against your skin to avoid a visible bump under thin tops.
  3. Sew in a small elastic loop: Hand-sew a ½-inch loop of clear elastic to the inside of each strap, about 2 inches from the shoulder. Thread your bra strap through the loop to anchor the bodysuit strap to your bra strap. This is invisible and reusable. Use a needle and thread that match the strap color. A single stitch through the elastic is enough; you don't need a full seam.
  4. Use the bodysuit's own gusset snaps: If your bodysuit has snaps at the gusset (like the Cosabella lace bodysuit), unsnap one side and re-snap it with the strap pulled slightly tighter. This shortens the overall length of the bodysuit, which takes slack out of the straps. Only do this if the bodysuit has adjustable or stretchy straps. Over-tightening can create a visible tug line at the crotch.
  5. Switch to a racerback clip: Buy a small racerback clip (a plastic or metal piece that converts two straps into a racerback shape). Clip both straps together at the back, near the shoulder blades. This changes the strap angle so they cannot slide off. Racerback clips work best on bodysuits with wide-set straps. They may not fit very thin spaghetti straps.

Product that makes the fix easier

  • Bodysuit: This sleeveless lace bodysuit has a plunging V-neckline and thong back with snaps at the cotton-lined gusset. The lace blend includes 64% polyamide and 12% elastane. The stretchy lace and minimal back coverage mean straps have less natural grip on your shoulders, so a proactive fix like a strap holder or fashion tape is almost always needed for all-day wear.
