Bottoms & pants

For bottoms, your waist and hip measurements from the table above are the best guide. Lengths and inseams differ per style — you'll find the exact length in the product description of each item. Wide-leg and relaxed fits are designed with extra room; for a tailored look in those styles, take your regular size.

Shoes & boots

Our footwear uses standard US sizing and generally fits true to size. Specific fit notes (e.g. "runs narrow") are listed on the product page where they apply.

Accessories

Bags, jewellery and hair accessories are one-size unless stated otherwise on the product page.

How to measure

Bust: measure around the fullest part of your chest, keeping the tape level.

Variant

An hourglass illusion — a sleek black mermaid maxi with sculpting white contour lines.

The curved contrast lines around the waist visually cinch and shape, while the fitted mermaid silhouette flows into a naturally flared hem at the ankle. Minimalist black-and-white, maximum impact.
