Category Fit Notes
Dresses
Dress fit may vary depending on fabric, cut and silhouette. Bodycon and fitted styles may feel more sculpted, while loose or flowing styles may offer a more relaxed fit.
Sets and Two-Piece Styles
Please check whether the top and bottom are intended to fit close to the body or more loosely. If you are between sizes and the set is fitted, we usually recommend sizing up.
Activewear and Stretch Styles
Stretch fabrics are designed to contour the body. If you prefer a more relaxed fit, or if you are between sizes, you may prefer to size up.
Outerwear
Coats and jackets may be designed to fit over layers. If you plan to wear knitwear or thicker garments underneath, you may prefer a slightly roomier fit.
Swimwear and Intimate Styles
For hygiene reasons, please review both the fit information and returns policy carefully before purchasing.
Fit Tips
- If you are between sizes, choose based on how you like your clothes to fit.
- For fitted styles, choose the larger size if you want extra comfort.
- For relaxed styles, you may prefer your usual size.
- If the fabric has little or no stretch, check the product page carefully before ordering.
