A good bra is an investment, and how you care for it decides whether it lasts six months or three years. This guide covers washing, when to replace, and how to fix the two most common bra annoyances, digging straps and poking underwires, for good.
If problems persist after these fixes, it’s usually a sizing issue, check the fitting and sizing guide.
How to Wash Bras (and Make Them Last)
Hand-washing is gentlest: cool water, mild detergent, a gentle squeeze, then reshape and air-dry flat. If you machine-wash, always use a lingerie bag, fasten the hooks, pick a delicate cycle, and never tumble dry, heat destroys elastic. Rotate bras and give each a day’s rest to recover its stretch.
- Hand-wash in cool water with mild detergent when you can.
- Machine: lingerie bag, hooks fastened, delicate cycle.
- Never tumble dry: air-dry flat, heat kills elastic.
Shop lingerie wash bags.
When to Replace Your Bras
Most bras last six to twelve months of regular wear. Replace yours when the band stretches out (you’re on the tightest hook and it still rides up), the cups lose shape, wires poke through, or straps won’t stay tight. A worn-out band means lost support, no matter how nice the bra looks.
- The 6-month rule: heavy-rotation bras wear out fastest.
- Replace when: band is loose on the tightest hook, cups sag, wires poke.
- Rotate several bras to extend every one’s life.

Stop Bra Straps Digging In
Digging straps almost always mean the band isn’t doing its job. Tighten the band fit first (usually a smaller band), then loosen the straps, they should only fine-tune, not carry the weight. Cushioned or wider straps and a racerback style spread the load for fuller busts.
- Fix the band first: a firm band takes weight off the straps.
- Loosen straps so they support, not carry.
- Choose wide, cushioned or racerback straps for heavy busts.
Shop wide cushioned strap bras.
Fix Poking Underwire
A wire that pokes out is usually a fit or wear issue. If the cup is too small, the wire sits on tissue and works loose, size up the cup. If the bra is just old, the casing has worn through; you can temporarily patch it with moleskin or a wire guard, but a poking wire is your cue to replace.
- Too-small cup pushes wires onto tissue, size the cup up.
- Temporary patch: moleskin or a fabric wire guard.
- Persistent poke means the bra is worn out, replace it.
Shop wire-free bras.
Frequently Asked Questions
How often should I replace my bras?
Every six to twelve months of regular wear. Replace sooner if the band rides up on the tightest hook, the cups lose shape, or wires poke through, that means lost support.
What’s the best way to wash a bra?
Hand-wash in cool water with mild detergent, then reshape and air-dry flat. If machine-washing, use a lingerie bag, fasten the hooks, choose a delicate cycle and never tumble dry.
Why do my bra straps dig into my shoulders?
Because the band isn’t carrying enough weight. Tighten the band fit (often a smaller band), loosen the straps, and choose wider cushioned or racerback straps.
How do I stop an underwire from poking out?
If the cup is too small, size up so the wire sits on your ribs. If the bra is old and the casing has worn, patch temporarily with moleskin, but a poking wire usually means it’s time to replace.
