How do I stop a strapless bra from sliding?
A strapless bra stays up through a snug band, not through straps.

A strapless bra has to hold itself up, so the band must be snug and the cups must fit; Lace Index stocks 2,491 sexy lingerie styles in S–3XL, with selected 4XL, from $9.90 to $47.90, shipped in plain packaging with 14-day returns. If it slides, the band is usually too loose or the cup shape is wrong.

Pieces for this answer.
01
Band and cup
The band should feel tighter than a normal bra band, with room for one finger, not two. A cup that is too small pushes the bra down. Try a smaller band or a larger cup before adding tape.
02
Skin and tape
Clean, dry skin holds better than moisturised skin. If the bra still slips, fashion tape at the band or a silicone-backed style can help. Test it for an hour before a long event.
03
The band has to do all the work
A strapless bra has no straps to carry the cups, so the band must be firm enough to hold the whole piece. Fasten it on the loosest hook and check that it stays level when you lift your arms. If it slides down, try a smaller band before adding tape.
04
Cup shape and coverage
A cup that is too small pushes the bra down; a cup that is too shallow can fold at the top. A full-coverage or demi shape with a firm lower cup usually holds better than a soft triangle. Check that the centre front sits close to the body and the wire does not press into the ribs.
05
Skin preparation
Clean, dry skin holds better than moisturised or powdered skin. Apply lotion well before dressing and let it absorb. If you use body oil, keep it away from the band area. A quick wipe with a dry towel can improve grip without irritating the skin.
06
Tape and silicone
Fashion tape can secure the band or the cup edge for a short event. Test it on a small area first, and remove it slowly with warm water. Silicone-backed bands grip without adhesive; keep them clean and let them air-dry so the surface stays tacky.
07
Test it before the event
Wear the bra for an hour at home, sit, raise your arms and bend forward. If it moves, fix the fit before you leave. Take tape or a spare bra for a long day, and avoid pulling the band down when you adjust it.
08
Dress neckline and back
A straight neckline needs a clean cup edge; a backless dress needs a band that sits low and stays put. Check the back height of the bra against the dress before the event. A low-back converter can help, but it changes the band tension, so test it for an hour first.
09
Heat, movement and long events
Heat and movement reduce grip. For a long event, choose a silicone band, keep the skin dry and take tape for a quick fix. Avoid pulling the bra down when it slips; lift the band back into place and press it against the skin.
10
Choosing the right size
Start with your underbust measurement and the band size you wear in a normal bra, then go down one band if the strapless style runs loose. Check the cup with the band fastened and the straps off. If the cup collapses or the centre front lifts away, the cup is too small or too shallow; if the band slides, the band is too large.
11
Backless and low-back dresses
A backless dress needs a bra with a low back or a stick-on shape; a standard strapless band may show above the fabric. Check the back height against the dress and test the bra with the dress on. If the dress is very low, a backless or adhesive style may be the only clean option.

Questions
Quick answers.
How do I stop a strapless bra from sliding?
Should it feel tight?+
Snug, yes; painful, no.
Does tape work?+
It can, on clean dry skin; test first.
Why does it slide when I sweat?+
Moisture reduces grip; try a silicone band or tape.
How tight should a strapless band be?+
Snug enough to stay level with one finger of room, not so tight that it digs in.
Is fashion tape safe for sensitive skin?+
Usually, if you patch-test first and remove it slowly. Stop if the skin becomes red or itchy.
What if I sweat?+
Moisture reduces grip. Blot the skin, use a silicone band and avoid heavy lotion before wearing.
