A blouse is the most fit-sensitive garment most women order. It sits close to the body, it is worn for hours, and a centimetre wrong at the shoulder or the armhole is felt all evening. Tailors usually ask for around eleven measurements, and most of them can be taken at home with a soft tape and a mirror. This guide explains each one in the words tailors actually use, so you can give accurate numbers, or check the ones you are given.

Three decisions to make before you measure

  1. Wear the bra you will wear with the blouse. A padded or push-up bra changes the bust and the position of the fullest point. A bralette changes neither. Measure in the exact one, and tell your tailor which it is.
  2. Settle the style. A plain fitted blouse, a princess-cut, a padded blouse with cups, a sleeveless one and a backless one each need slightly different numbers. Decide before you measure, not after.
  3. Decide the neckline and the sleeve. Front and back neck depth, and the sleeve length you want (short, elbow, three-quarter or full), are choices, not measurements of your body.

The eleven blouse measurements

Blouse measurements, what they are and how to take them
MeasurementWhat it isHow to take it
Blouse lengthHow long the blouse isFrom the top of the shoulder beside the neck, straight down over the bust to where you want the hem
ShoulderWidth across the backFrom the bone at one shoulder edge to the other, straight across the back
Sleeve lengthHow long the sleeve isFrom the shoulder bone to where the sleeve should end, with the arm relaxed
Sleeve roundWidth of the sleeve at the upper armAround the fullest part of the upper arm, relaxed
Armhole (round)The opening the sleeve is sewn intoAround the shoulder joint and through the armpit, arm relaxed at your side
Upper chestGirth above the bustAround the chest above the bust, under the arms and across the back
BustGirth at the fullest pointAround the fullest part of the bust, tape level at the back
Underbust (waist)Girth just under the bustDirectly under the bust, where the bottom of the blouse will sit. Snug, not tight
Front neck depthHow low the front neckline goesFrom the base of the neck at the shoulder line, straight down the front to the depth you want
Back neck depthHow low the back neckline goesFrom the base of the neck at the back, down the spine to the depth you want
Dart point (apex)Where the fullest point of the bust sitsFrom the shoulder line beside the neck down to the fullest point of the bust

How to take them, in order

  1. Stand straight in front of a mirror, in your bra and a thin fitted top, arms relaxed at your sides.
  2. Take the upper chest, then the bust, then the underbust, keeping the tape level all the way round. Check in the mirror that it has not climbed at the back.
  3. Take the shoulder, ideally with a helper. On your own, measure the shoulder seam on a blouse that fits you well.
  4. Take the armhole and sleeve round, then the sleeve length you want.
  5. Take the blouse length, then the front and back neck depths.
  6. Take the dart point last. It is the hardest to get right alone, so ask for help.

Checks that catch a wrong number

Before you send numbers to a tailor, run these three sanity checks. They take a minute and catch most mistakes.

  • The order must make sense. Bust should be at least as large as the upper chest, and the underbust should be clearly smaller than the bust. If it is not, re-measure.
  • The armhole is larger than the sleeve round. The armhole goes through the armpit and around the joint, so it is always the bigger of the two.
  • Measure twice. If two readings of the same measurement differ by more than a centimetre, take a third and use the middle one.

How the style of blouse changes the measuring

  • Padded or cup blouse. Measure in the bra you will wear, and tell the tailor whether you want lined cups. The dart point matters most here.
  • Princess-cut. The seams follow the curve of the bust, so the dart point and the bust need to be accurate to the centimetre.
  • Sleeveless. The armhole is the critical number. Too large and it gapes, too small and it cuts in.
  • Deep or backless necklines. Give the back neck depth carefully and ask about ties or stays, because there is less fabric holding the blouse in place.
  • Heavy embroidery or zari. Ask for a trial fitting before the work is finished, because embroidered fabric is much harder to alter afterwards.

When to get measured in person

Take your own numbers to compare quotes and to brief a tailor. For a bridal blouse, a corset-style blouse or anything with structured cups, let the tailor measure you in person as well, and book a trial fitting. A tape cannot see how one shoulder sits lower than the other, or how your posture changes where the bust falls, and a good tailor will adjust for both. You can also start with our free measurement scan: choose the women's chart and it includes bust, underbust and armhole. It is an estimate, so use it as a starting point and have your tailor confirm the numbers.

Frequently asked questions

What is the standard blouse length?

It varies with style and body. Many tailors work with a length of roughly 13 to 16 inches (33 to 41 cm) from the shoulder to the hem for a standard blouse, shorter for crop styles and longer for jacket styles. Measure your own instead of assuming a standard.

Which bra should I wear while measuring for a blouse?

The one you will wear with the blouse. A padded or push-up bra changes the bust and the dart point, and a bralette changes neither. Mention it to your tailor as well.

What is a dart point?

It is the distance from the shoulder, beside the neck, down to the fullest point of the bust. Tailors use it to place the darts so the fabric follows the curve instead of pulling across it.

Can I order a blouse without a trial fitting?

You can, but the risk is yours: a first blouse from a new tailor rarely fits perfectly. Ask for a trial before the final finishing, and keep the measurements you gave so you can tell whether a problem came from the cutting or from the numbers.

What is the difference between bust, upper chest and underbust?

Upper chest is the girth above the bust, bust is the girth at the fullest point, and underbust is the girth directly below the bust. Bust is the largest of the three.
