With an adjustable triangle or string bikini top, you can change the neckline and strap placement by tying the strings in different ways. What works depends on the top’s construction: strap length, loops, clasps and fixed sections can rule out some styles. Start with ties that reach comfortably; don’t force a knot or route that pulls on the cups or your body.
Before you restyle your bikini top
- Use a top with adjustable straps long enough to follow the route you want. A fixed-band, underwire, clasp-only or short-strap top may not support these variations.
- Lay the top flat and identify which strings attach to the cup tops and which attach to the cup bases. Designs differ, so adapt the steps to the ties your top actually has.
- After tying, check that the cups stay positioned and that knots do not press uncomfortably. These are styling ideas, not tested fit or safety methods. For swimming or active use, follow the garment’s instructions and check that the top stays in place before entering the water.
The classic triangle/string construction is the basis for the variations below. Retailer guidance also distinguishes fastening options by top style, so not every method transfers to every bikini (Bond-Eye Swim).
9 ways to tie a bikini top
1. Classic triangle halter
- Position the cups upright, with the triangle points facing up.
- Tie the upper straps behind your neck.
- Tie the lower straps at mid-back.
- Adjust the cups and knots until the top sits comfortably.
2. Upside-down halter
- Turn each triangle cup upside down so the usual base edge is repositioned.
- Place the cups over your chest and tie the upper straps behind your neck as a halter.
- Secure the lower straps at your back, then adjust the cups.
This variation is described for triangle tops; the changed cup orientation alters the look and may not suit every cut or construction (Sports Illustrated Swimsuit; Marks & Spencer).
3. Tie-front
- Move the cups apart to make room for the front tie.
- Route the long center or upper straps around your body so they meet at the front.
- Tie them between the cups, and secure the lower straps at the back.
- Check that the cups remain in position and that the strap route does not pull.
The exact route depends on how the straps attach to your top; if the strings cannot reach the front comfortably, choose another style.

4. Keyhole bandeau
- Turn the top upside down and position the cups across your chest.
- Bring the upper straps to the front and knot them between the cups.
- Leave a small opening beneath the knot for the keyhole effect, and secure the remaining ties at the back as the design allows.
The center opening changes the coverage and silhouette. Do not tighten the knot to the point that it shifts the cups.
5. Cross-front halter
- Place the cups conventionally.
- Cross the upper straps over your chest, routing each toward the opposite side.
- Bring the straps up and tie them behind your neck.
- Secure the lower straps at your back and adjust the cups.
6. T-back
- Arrange the cups and upper straps as a halter.
- Bring the lower straps up toward the nape of your neck.
- Tie or connect the lower straps to the upper straps at the nape to create a T-like line at the back.
This requires enough length and a strap arrangement that can meet comfortably behind the neck. If the connection pulls at the cups or neck, untie it.

Use this route only if the straps reach without constriction; the angle should not come at the cost of comfortable cup placement.
8. Wrap-around
- Position the cups and secure the ties needed to hold them in place.
- Use the excess strap length to wrap around your torso once, or more if the strings allow.
- Secure the ends where they meet without pulling the cups out of position.
Stop if the straps pull, constrict or feel uncomfortable. Wrap length is determined by the garment, not by a fixed number of turns.
