Pieces for this answer.
01
Adjust and check
Shorten each strap by the same amount and check in a mirror. The strap should sit flat, not dig in. If one shoulder slopes more, a racerback converter or a style with a closer-set strap can help.
02
When it is the band
If the band slides down at the back, the straps have to take the weight and will slip. A smaller band or a tighter hook often solves it without shortening the straps further.
03
Check the strap length first
Fasten the bra, loosen both straps completely, then tighten each one only until the cup sits flat. A strap that is too long will slide off the shoulder; a strap that is too short will dig in and pull the band up. Adjust one side at a time and raise your arms to check that the strap stays in place without lifting the band.
04
Check the band before the straps
If the band is loose, the straps have to carry the cups and they will slip. Fasten on the loosest hook, check that the band sits level and try a smaller band if it climbs. A firm band keeps the strap position stable, even on narrow or sloping shoulders.
05
Strap position and shoulder shape
Straps set close to the neck suit narrow shoulders; straps set wider suit broader shoulders. If your shoulders slope, a racerback converter or a cross-back style can keep the straps in place. A multi-way bra gives you more options, but the band still has to fit.
06
Fabric and strap width
A narrow elastic strap is more likely to slide than a wider strap with a soft edge. Silicone strips or a textured underside can help. If the strap digs in, the cup may be too small or the band too loose, so check those before changing the strap.
07
When the bra is the problem
If the band fits, the cup fits and the straps still slip, the strap placement may be wrong for your shoulders. Try a different style rather than tightening the straps further. A bra that needs constant adjustment is not the right shape for you.
08
Racerback and cross-back
A racerback clip pulls the straps toward the centre and keeps them on narrow or sloping shoulders. A cross-back style does the same without a clip. Try the converter with the bra you own before buying a new style; the band still has to fit.
09
Multiway straps
A multiway bra lets you move the straps to a halter, cross-back or one-shoulder position. Check that the strap attaches securely and that the cup still sits flat. A multiway strap is only useful if the band is firm.
10
Strap material
A soft, wider strap with a textured or silicone underside grips better than a narrow shiny strap. If the strap digs in, the cup may be too small or the band too loose. Fix the fit before changing the strap.
11
When to replace
If the straps have lost their elasticity or the adjusters slide, replace the bra. A stretched strap cannot be tightened enough to stay in place. Check the band and the cups at the same time.
12
A final check
Fasten the bra, raise your arms and turn your shoulders. If a strap slips, adjust the length and the position. If it still slips, try a racerback or a different style.
13
A stable fit
A stable strap starts with a firm band. Fasten on the loosest hook, check that the band sits level, then adjust the straps only until the cup sits flat. If the straps still slip, try a racerback converter or a cross-back style. A wider strap with a textured underside grips better than a narrow shiny strap. If the strap digs in, the cup may be too small or the band too loose. Fix the fit before tightening the strap. A bra that needs constant adjustment is the wrong shape, not a strap problem.

Questions
Quick answers.
Why do my bra straps keep slipping?
How tight should straps be?+
Snug enough to keep the cup in place, not tight enough to leave marks.
Why only one strap?+
Shoulders are often uneven; adjust each side separately.
Can I cross the straps?+
A converter can help, but check the band fit first.
