How to Measure Yourself
For the most accurate results, measure yourself in your underwear or lightweight clothing. Use a soft measuring tape and stand in a natural position.
Bust
Measure around the fullest part of your bust, keeping the measuring tape parallel to the floor.
Waist
Measure around your natural waistline, which is the narrowest part of your torso, typically above your belly button.
Hips
Measure around the fullest part of your hips, usually about 8 inches below your waistline.
Sizing Tips
- If you're between sizes, we recommend sizing up for a more comfortable fit.
- Our maxi dresses tend to run slightly longer, perfect for taller frames.
- For fitted styles like bodycon dresses, consider your body shape as well as measurements.
- Palazzo pants are designed to be loose and flowy - refer to waist measurements for the best fit.
- Kimono styles are meant to have an oversized fit.
