How to Choose Your Size
- Start with your current bust, waist, and hip measurements rather than guessing from another brand’s size.
- Use the size that matches your fullest measurement when choosing fitted tops, dresses, swimwear, or structured styles.
- For bottoms, compare both waist and hip measurements, then review the product page for cut, rise, stretch, and leg shape.
- For bras, measure underbust and bust, then choose the closest band and cup range in the bra chart.
Measuring Tips
Bust
Measure around the fullest part of your bust while keeping the tape level and comfortably close to the body.
Waist
Measure around the narrowest part of your waist without pulling the tape too tightly.
Hips
Measure around the fullest part of your hips and seat while standing naturally.
Underbust
Measure directly under the bust, keeping the tape straight around your body.
Fit Notes & Between-Sizes Advice
If your measurements fall between two sizes, consider the fabric and fit of the item. For close-fitting or non-stretch styles, the larger size may feel more comfortable. For relaxed, stretchy, or oversized styles, the smaller size may give a cleaner fit.
Always review the individual product details before ordering. Product pages may include fit notes, fabric information, length, stretch, or style-specific guidance that can affect how a garment feels when worn.
