What dress size am I? A practical example using dress size calculator

Now that you know how to measure dress size, let’s use a practical example to find out how the dress size calculator works.

  1. Let’s see how to measure dress size for Anne.
    She made the following measurements of her body expressed in centimeters:
  • Bust: 95 cm
  • Waist: 80 cm
  • Hips: 102 cm

Don’t worry about different length units. Our calculator has a built-in length conversion to make everything easier.

  1. Once she inputs all necessary information into the dress size calculator, she finds out that:
  • Ann wears size 10 in the USA.
  • She should go for a dress size 14 in the UK.
  • In Europe, Ann should choose size 42 when buying a dress.
  • The international symbol for her dress size is M.




How do I figure out my dress size?

You can figure out your dress size by following these steps:

  1. Measure your body accurately. Use a measuring tape to measure your chest, waist, and hips.
  2. Look up for a dress size chart.

    Though sizes are more or less standardized, each brand has its own unique size chart. Look up the size chart for the brand of dress you want to buy.

  3. Compare your body measurements to the size chart to determine which size is the closest match.

What’s a 38 EU dress size equivalent to in US sizing?

It’s equivalent to a US size 6. The measurements associated with this size are:

  • Bust: 86-89 cm (33.5″-35″);
  • Waist: 69-72 cm (26.5″-28″); and
  • Hips: 95-97 cm (37″-38″).

You can always use Omni’s dress size calculator to easily convert your size to any other standard sizing system.

Is a UK size 12 a small or a medium?

It’s a medium or M. Keep in mind that letter sizes encompass two numeric sizes, e.g., a medium runs for both 12 and 14 UK, or 90-97 cm (35″-38″) for bust, 73-81 cm (28″-32″) for waist and 98-104 cm (38″-41″) for hips.
