A step-by-step triangle bra care routine for hand washing, drying, and storing lace so it keeps its shape and softness for years.

Quick answer

Hand wash your triangle bra in cool water with a drop of gentle detergent, press the water out instead of wringing, dry it flat or hanging by the center gore, and store it folded with the cups nested so nothing presses on the lace. Skip the dryer and never soak it overnight. That routine protects the elastic, the lace edges, and the triangle shape far better than any spot-cleaning shortcut.

Why triangle bras need a different routine

A triangle bra is usually cut from a single piece of lace or tulle with thin straps and minimal seams. That construction is what makes it feel light, but it also means the fabric has little internal structure to hold its shape once it is wet. The lace on a style like SIN is a good example: opalescent tulle at the front and back with embroidered leaf motifs at the sides, finished with folded edges. Those folded edges and the embroidery are the first things to distort if you twist or scrub the bra.

The other weak point is the elastic. Heat and detergent residue break down elastane over time, which is why a bra that fit well in month one can feel loose by month six. Cool water and a short soak protect the elastic as much as the lace.

What you actually need at the sink

You do not need a specialty kit. A clean basin or bowl, cool water, a pH-neutral or lingerie-specific detergent, and a towel are enough. Avoid wool wash with lanolin, fabric softener, and chlorine bleach; all three leave a coating that dulls lace and weakens elastic. If you only have regular laundry detergent, use a fraction of the normal dose and make sure it dissolves fully before the bra goes in.

Keep a separate small mesh bag for bras if you ever machine wash on a delicate cycle as a backup. A mesh bag does not make hot water or a spin cycle safe, but it does stop straps from tangling with other garments.

Your step-by-step triangle bra care routine

1. Fasten the hooks and check the cups: Close the back hooks before washing so they cannot catch on lace, then check the cups for any loose thread or pulled embroidery. If you find a snag, stop and repair it first; washing will make it worse. Checkpoint: hooks closed, no loose threads.
2. Fill a basin with cool water and a small amount of gentle detergent: Water should be cool to the touch, not warm. Add a teaspoon or less of pH-neutral detergent and swirl it in until fully dissolved. Common mistake: pouring detergent directly onto the lace, which can leave a residue mark. Checkpoint: detergent fully dissolved before the bra goes in.
3. Submerge and soak for no more than 10 minutes: Let the bra sit fully underwater and gently press it down a few times so water moves through the fabric. Do not rub, twist, or scrub the lace. Ten minutes is enough for normal wear; longer soaks risk dulling the elastic. Checkpoint: set a timer so you do not forget it.
4. Rinse in cool running water until it runs clear: Lift the bra out and rinse under a gentle stream, or refill the basin with clean cool water and press the bra through it twice. Squeeze the cups very lightly to help water move through, but never wring. Checkpoint: no slippery feel left in the fabric.
5. Press water out in a clean towel: Lay the bra flat on a dry towel, fold the towel over it, and press down with your palms. Do not twist the towel. This removes most of the water without stressing the straps or lace. Checkpoint: bra is damp, not dripping.
6. Dry flat or hang by the center gore, never by the straps: Lay the bra flat on a drying rack, or hang it by the center gore if you have space. Keep it out of direct sun and away from radiators. Hanging by a strap stretches that strap and can pull the cup out of shape. Checkpoint: straps are not bearing the weight of the wet bra.
7. Store folded with cups nested: Once fully dry, fold the bra in half with one cup inside the other and stack it at the top of a drawer, not under heavier items. For triangle bras with folded edges, this keeps the lace from creasing against itself. Checkpoint: nothing heavy resting on the cups.

Product facts that affect how you care for it

MISS LEJABY: High-waisted lace brief with elastic lace, graphic elastic bands at the waist, and a soft elastic waistband designed for hold without marking. The elastic waistband is the part most affected by heat and detergent residue, so wash this piece the same way you wash the matching triangle bra and never leave it soaking.
SIN: Brief in opalescent tulle with embroidered leaf motifs at the sides and folded-edge finishing. Folded edges and embroidery snag easily, so keep this piece away from zippers, hooks, and Velcro in the wash and store it flat rather than crammed into a drawer.
EXTENSION DE SOUTIEN-GORGE: Bra back extender with a 2-hook attachment, up to 5 cm of extra comfort, 3 cm wide and 8 cm long. If your triangle bra feels tight around the back after washing, try an extender before assuming the bra has stretched out; it adds room without changing the cup fit.
