The colour-fastness test to do before any suit is stitched
An at-home colour-fastness test for suits and dupattas before stitching: how to check for bleeding and rub-off, what the results mean and what to do if colour runs.
InspirationWhy test before stitching
A suit that bleeds is annoying on its own. Once it has been stitched, bleeding can do more damage: a dark piping can run into a white kurta, a red kameez can stain the pale lining inside it, and a bright dupatta can mark a cream shalwar in the same wash. Testing the fabric before it is cut lets you, and your tailor, plan around the problem.
The test takes a few minutes and uses things you already have. It is a guide rather than a guarantee, and it is general advice: the garment’s care label always comes first, and every test should be done on a hidden area.
The test, step by step
Test each piece separately: the kameez, trouser and dupatta fabrics, any lining or contrast fabric, and embroidery threads if they are a different colour from the base.
- Choose a hidden spot: a corner of the trouser piece, the selvedge or an area that will fall inside a seam allowance.
- Dry rub: rub a clean white cloth or tissue firmly over the spot about ten times. Colour on the cloth means the dye may rub off onto bags, seats or pale clothes.
- Wet rub: dampen the spot with cool water and repeat with a fresh white cloth. Deep colours often show more when wet.
- Press test: dampen the spot, lay a white cloth over it and press with a warm iron for a few seconds, if the care label allows ironing. Colour on the cloth suggests what may happen in a warm wash.
- Water test: if you have a small offcut or a spare thread, drop it into a glass of cool water with a drop of your usual detergent for 15 to 30 minutes. Tinted water means the dye is loose.
Reading the results
- No colour at all: the fabric is probably colour-fast in normal washing. Still wash it with similar colours for the first few washes.
- A faint tint: common with new, deeply dyed cottons. Wash separately in cool water for the first few washes, with a colour-catcher sheet.
- Strong colour on the cloth or in the water: the dye is loose. Consider washing the piece on its own before stitching, or dry cleaning it, and think twice about pairing it with white or pale pieces in the same outfit.
- Embroidery thread bleeding: this is harder to deal with after stitching, so it is worth knowing before a pale lining or contrast piping goes behind it.
What to do if a fabric bleeds
Washing a bleeding plain piece on its own in cool water before stitching lets excess dye rinse out and shows you whether it settles. Our pre-washing guide explains how to do it without fraying the edges. Salt and vinegar are often suggested, but they do little to fix most modern factory dyes; separate washing and a colour-catcher sheet are more dependable.
Do not wash embroidered panels, zari, velvet or silk to test them. If they show colour on a gentle damp rub, dry cleaning is usually the safer route. And never leave a damp, bleeding fabric folded on itself or on other clothes, which is when most dye transfer happens. For everyday washing afterwards, see our care guide.
Tell your tailor what you found
When you ask for a quote, mention any bleeding on the stitching quote form, piece by piece. It affects design choices, such as whether a contrast piping, a pale lining or white trousers are sensible next to a strong colour. If you are unsure what your results mean, describe what you saw and we’ll suggest options in your quote. The custom stitching page explains how the rest of the process works.
Common questions
How do I know if my fabric will bleed?
Rub a damp white cloth firmly over a hidden area of the fabric. If colour transfers to the cloth, the dye is likely to bleed in the wash, so wash that piece separately in cool water.
Does salt or vinegar stop colours running?
Not reliably. They are common home remedies, but they do little to fix most modern factory dyes; separate cool washing and a colour-catcher sheet are more dependable.
Should I test embroidered fabric by washing it?
No. Use a gentle damp rub test on a hidden part of the embroidery instead. Washing an embroidered panel before stitching can pucker it, and embroidery that bleeds is usually safer dry cleaned.
