Blouse Size & Measurement Converter
Turn a bust measurement into the ready-made blouse size to ask for, an alpha size, and an approximate UK/US dress size — in centimetres or inches.
Your blouse size
Indian ready-made blouses are labelled by the bust inch, cut with a little ease built in. Brands and tailors vary — treat this as a starting point and check each label’s own chart before you buy.
From tape measure to label
The bust round is the one measurement that decides a ready-made blouse size. Because Indian blouses are labelled by the bust inch, the tool rounds your measurement to the nearest even number and hands you the size on the tag — then translates it into the alpha size and the rough UK and US dress equivalents so you can shop across charts with confidence.
Sizing is never perfectly standard between brands, so treat the result as your starting point. If you are having a blouse stitched rather than buying off the rack, take the size to your tailor along with your shoulder, waist, and length so the fit is built around your body, not a generic block.
Frequently Asked Questions
How are Indian blouse sizes numbered?
Ready-made blouses are labelled by the bust measurement in inches — a size 36 blouse is cut to fit a 36-inch bust, with a small amount of ease already built in. Sizes run in even numbers (32, 34, 36, 38…), so this tool rounds your bust to the nearest even inch to give the size to ask for.
Which measurement should I take?
Measure the bust round: the tape snug and level around the fullest part of the chest, under the arms, and across the shoulder blades at the back. Keep the tape parallel to the floor and don't pull it tight. That single number drives the blouse size; a good tailor will also want your shoulder, waist, and blouse length.
Are the UK and US dress sizes exact?
They are a guide, not a guarantee. This tool derives an approximate UK and US dress size from the bust so you can cross-reference international charts, but every brand cuts to its own block. Always check the specific label's own size chart, and when a garment falls between sizes, size up for a blouse you'll get altered.
The size feels between two — which do I pick?
If your bust lands between sizes, go up rather than down: a blouse can always be taken in at the side seams, but letting one out is limited by the seam allowance. If you plan to have it tailored anyway, the larger ready-made size gives the tailor more cloth to work with.
Educational guide only. Sizing varies between brands and tailors; always check the specific label’s own chart and, for a stitched blouse, rely on your own measurements taken by a tailor.
