How to measure dress
Every point, drawn on the garment so there is no guessing where the tape goes.
Quick answer
Lay the dress flat and measure six points: bust, waist, hip, top length, skirt length and hem, in that order of fit-impact. Bust leads, taken one inch below the armhole where most guides eyeball it. Hover or tap each step on the diagram to see exactly where the tape sits. Sizely turns those numbers into a size chart buyers trust.
A buyer holding your listing next to a dress in her closet looks at the bust first, then checks whether the waist hits where she wants and the length lands above or below the knee. On a one-piece, bust, waist and length all decide the fit at once, so missing one sends the wrong dress out. Generic guides stop at three points. This page draws all six on the actual garment, the same ones the buyer will check.
- A
Chest
The bust is the first thing a buyer checks on a dress, so it leads. Lay the dress flat and take it straight across the fullest part of the chest, roughly an inch below where the armholes meet the body. Tap this step to see the exact line, since reading too high catches the armhole and runs wide.Double it for the full bust circumference.
- B
Waist
Across the body at the narrowest point of the dress, usually where a seam or the natural waist sits. This is what tells a buyer whether the dress nips in or falls straight, so it matters as much as the bust on a fitted style.Double it for the full waist circumference.
- C
Hip
Across the widest part below the waist. On a fitted or bodycon dress this decides whether it slides over the hips; on an A-line it sets where the skirt starts to flare. Tap the step to see where the line sits.Double it for the full hip circumference.
- D
Length A
The top length, a single vertical run from the shoulder seam down to the waist seam. It tells the buyer where the waist of the dress will land on her own body, which is the number generic guides leave out.Recorded as-is. Do not double.
- E
Length B
The skirt length, measured from the waist seam straight down to the hem. Add it to the top length for the full dress, but listing the two parts separately tells a buyer whether the skirt is the long part or the bodice is.Recorded as-is. Do not double.
- F
Hem
Across the bottom opening of the skirt. A wide hem reads full and swingy, a narrow hem reads pencil or fitted, so it sets the silhouette at a glance.Double it for the full hem circumference.
Measure flat and never stretched. Smooth the dress on a table, keep the tape flat against the fabric, and let zippers and gathers sit naturally instead of pulling them tight. The four across points, bust, waist, hip and hem, double to a body circumference; the two length runs, top length and skirt length, are recorded exactly as measured.

Frequently asked
What dress size am I from my measurements?
Match your own bust, waist and hip to the flat chart, then double the flat bust, waist and hip numbers to compare against your body. Sizing differs by country, so a US 8 is not the same as a UK or EU number. For the full US, UK and EU letter-to-number map, see our international dress size chart.
Which measurement matters most on a dress?
Bust usually leads, because a dress that is tight across the chest cannot be fixed by anything else. Waist comes next on fitted and wrap styles, and length decides whether it reads as a mini, midi or maxi. On a one-piece all three matter together, which is why this guide lists every point rather than just the bust.
Do I double the bust and waist on a dress?
For the flat chart number, no, record it exactly as measured across the laid-flat dress. To estimate the body circumference, double the bust, waist, hip and hem, since each is taken across a single folded layer. The two length runs, top length and skirt length, are single passes, so the flat number is already the real number.
How do I measure dress length?
Measure it in two parts. Top length runs from the shoulder seam down to the waist seam, and skirt length runs from the waist seam to the hem. Add them for the total. Splitting the length tells a buyer where the waist lands and how long the skirt falls, which a single shoulder-to-hem number hides.
Should I measure a dress in inches or centimeters?
Either is fine, as long as you stay consistent and label the unit. Sellers shipping across borders do best showing both, since a buyer in one market thinks in inches and another in centimeters. Sizely lists both on every chart so no buyer has to convert in her head.
Why do dress sizes vary so much between brands?
There is no enforced standard for dress sizing, so each brand drafts to its own block and target customer. That is why the same labeled size can fit differently from two makers. A measured flat chart sidesteps the label entirely and gives the buyer numbers she can check against a dress she already owns.
