How to Measure Your Bra Size at Home: The Complete Fit Guide
Up to 8 in 10 women wear the wrong bra size. Here's how to measure accurately at home, decode the sister-size chart, and know exactly when a bra fits.

A good bra can cost as much as a nice dinner out — but unlike dinner, it should last for years. The difference between lingerie that survives three months and lingerie that survives three to five years is almost entirely down to how you wash, dry and store it.
Here's the complete care routine we recommend for every SANTCARA piece, from silk slips to everyday cotton.
Lingerie is engineered from delicate fibres, fine elastics and small fastenings, all under regular tension. Harsh detergent, hot water and tumble drying break down elastane — the stretch fibre that gives a band its support — long before the fabric itself wears out. Gentle care protects the stretch, the shape and the colour all at once.
It sounds fussy, but hand-washing takes about three minutes and dramatically extends the life of your favourite pieces — especially bras, silk and lace.
Treat silk and lace like you'd treat a cashmere jumper: cool water, gentle detergent, no wringing, dry flat.
Real life happens, and most everyday cotton and modal pieces machine-wash perfectly well. To do it safely:
As a rule: cotton and modal are machine-friendly on cold; silk, fine lace and structured underwire bras are happiest hand-washed.
This is where most damage happens — and it's the easiest step to get right. Never tumble dry lingerie. Heat is the enemy of elastane, and a single hot cycle can permanently slacken a band.
How you store bras matters as much as how you wash them:
Elastane needs time to recover its stretch. Wearing the same bra two days running keeps it under constant tension and wears it out faster. Ideally, rest a bra for a day between wears and rotate through a few favourites. A capsule of well-cared-for pieces will outlast a drawer full of neglected ones.
Every two to three wears is plenty for most people, unless you've been exercising or it's very hot. Over-washing wears elastic out faster.
Spot-test first on a hidden area. For silk, dilute any treatment heavily and rinse quickly; harsh removers can leave water marks.
If the fabric is still sound, move to a tighter hook. If it's stretched beyond that, it's usually a sign the elastane has worn — time for a replacement, and gentler care next time.
