FIONA SECRET CLOSET · THE FIT EDIT
Find your best fit
Our collection includes styles made by designers and suppliers in different countries. A Small in one brand may fit differently from a Small in another. Always use the measurements on the individual product when provided.
European (EU), UK and US labels do not always match. Chinese and other Asian manufacturers do not follow one universal size conversion. Do not choose only by the letter on the tag—compare bust, waist and hip measurements before ordering.

How to measure
Bust
Wrap a flexible measuring tape around the fullest part of your bust. Keep the tape level and comfortably snug.
Waist
Measure around your natural waist, usually your narrowest point, without pulling the tape tightly.
Hips
Stand with your feet together and measure around the fullest part of your hips and seat.
Special-occasion gowns & custom Diamond Dresses
Fitted gowns may have little stretch, and custom-made dresses may require additional measurements. If you are between sizes or shopping for a special event, contact us with your bust, waist, hips, height, and the product name before ordering.
