Size Guide


I know, we're all different! But if there is one thing Gwyllem does well, its fit. Thats the beauty of stretchy fabric.

What size do you typically wear? Generally speaking, thats your size. 

One question we get asked a lot is; ‘what's your sizing like?’ we call it true. However, sizing is generally shifting upwards these days. So if you wear labels that have roomier sizing, you might want to go up a size - remember, sizes are just numbers we made up. 

Consider how you'd like your garment to fit. Do you prefer a fitted look or more relaxed? Most of our current styles are designed to be worn fitted. So if you prefer a more relaxed vibe, get the size up.

If you're unsure of what size to order, please contact us for advice. It's helpful to tell us the sizes of clothes you already own and your most common fit issues. 

  • Most Gwyllem dresses are fit and flare styles, so the main measurement you need to look at is your bust and waist.
  • Skirts and pants come with a stretch waistband, designed to accommodate size fluctuations. The main measurement here is low hip (or around your bum and the top of your thighs). 

A note on size 18-22. If you normally shop plus brands, or brands that have generous sizing you might find that Gwyllem sizing is much smaller. This is because we have simply extended our range from the standard 8-18 range. We highly recommend checking your measurements against this chart if you typically wear sizes 18 and upwards. 

Measuring tips:

Bust: To measure the fullest part of your bust, ensure the tape measure is even and horizontal across the back. Measure wearing a bra you would typically wear.

Waist: Measured at the smallest part of your torso.

High hip: Measured about 10cm below your waist, usually at the hip bones.

Low hip: Measured around the fullest part of your bum, about 20cm below the waist.

Tip: When measuring yourself, if possible do so in front of a mirror to ensure the tape measure is horizontal. Hold the tape measure close against you body but not too tight.
