Find Your Perfect Fit

Every Muse Casey piece is designed with intention. Use our size charts and measuring tips to choose the size that feels right for you — in both centimeters and inches.

How to Measure

3 Simple Steps

Measure over your undergarments with a soft tape. Keep it snug, not tight.

1

Bust

Measure around the fullest part of your chest, keeping the tape level across your back and shoulder blades.

2

Waist

Measure around your natural waistline — the narrowest part of your torso, usually just above the belly button.

3

Hip

Measure around the fullest part of your hips and bottom, keeping the tape parallel to the floor.

By Category

How Each Category Fits

Every product page also lists specific fit notes for that piece.

Dresses

Dresses & Midi

Our dresses are cut to skim the body rather than cling. Knit styles have stretch; woven linen styles are structured and true to size.

💡 Between sizes? Take your usual size — linen relaxes beautifully after the first wash.
Tops & Blouses

Tops & Blouses

Fit is determined by the bust and shoulder. If you are between sizes, compare the shoulder width on the product page.

💡 Not sure? Measure a top you already love and compare with our garment measurements.
Bottoms & Pants

Bottoms & Trousers

Choose by your larger measurement — waist or hip. High-waisted styles fit best when chosen for the hip.

Size FAQ

What if I’m between sizes?+
We recommend sizing up. Garments in natural fabrics (linen, organic cotton) have a little give and will drape beautifully in the next size up. If you’re buying a knit piece, you can comfortably take either size.
Can I exchange if the size doesn’t fit?+
Yes — free size exchanges within 30 days of delivery. Items must be unworn with tags attached. Start an exchange from your account or contact our team at care@musecasey.com.
Do the measurements shrink after washing?+
Our linen is pre-washed during production to minimize shrinkage. Always follow the care label — cold wash and line dry to keep your pieces in perfect shape.
Are garment measurements listed on each product?+
Yes. Every product page includes a detailed size & fit tab with exact garment measurements in both cm and inches for every size.
