Corsets are made to fit close to the body, so the right size makes all the difference between a top you love and one that sits in the drawer. The good news: finding your size takes about two minutes and a soft measuring tape. Every Glamwiz corset comes in sizes XS to 5XL, so this guide works whether you are petite, curvy or plus size.
What you need
- A soft (fabric) measuring tape
- A mirror, or a friend to help
- The underwear you plan to wear with your corset
Measure your body, not a piece of clothing, and keep the tape snug but not tight. It should sit flat against your skin without digging in.
Step 1: Measure your bust
Wrap the tape around the fullest part of your chest, keeping it level under your arms and across your back. Breathe normally and note the number.
Step 2: Measure your natural waist
Find the narrowest part of your torso, usually just above your belly button. Stand relaxed (no sucking in) and measure all the way around. For corsets, this is the most important number.
Step 3: Measure your hips
Stand with your feet together and measure around the fullest part of your hips and bottom. This matters most for longer styles and peplum corsets.
Step 4: Match your numbers to the chart
Compare your measurements with our size chart below. Bust, waist and hips are body measurements in inches, with centimetres in brackets.

What if my measurements fall in different sizes?
This is very common. Because a corset is shaped around the waist, go with your waist size first. If your bust is noticeably larger than that size, a halter or adjustable style will usually be more comfortable than a strapless bustier.
Between two sizes?
- For all-day or all-night comfort (dinners, dancing, long events), choose the larger size.
- For a firmer, more snatched look, choose the smaller size.
Plus size corset tips
- Look for structured boning: it shapes and supports without squeezing.
- Halter and wide-strap styles such as Pink Shimmer and Golden Hour give extra support across the bust.
- Underbust corsets are the easiest place to start: you wear them over a shirt, tee or dress, so fit at the bust does not matter. Browse underbust corsets.
