Learn how to choose the right size and get the best fit from your ChiChi Modal Brief 4 Pack. Step-by-step guide with common mistakes to avoid.
Quick answer
For the ChiChi Modal Brief 4 Pack, start by measuring your natural waist and hips, then use the brand's size chart to match your larger measurement. If you're between sizes, choose the larger size for a comfortable, smooth fit under clothes.
Why sizing matters for high-waisted briefs
The ChiChi Modal Brief is a high-waisted, curve-hugging bikini brief with a thick, sculpting waistband. Getting the size right ensures the waistband stays in place without rolling or digging in, and the semi-seamless finish stays smooth under clothes.
How to find your ChiChi Modal Brief size
- Measure your natural waist and hips: Use a soft measuring tape. For your waist, measure around the narrowest part (usually just above your belly button). For your hips, measure around the widest part (about 20 cm below your waist). Write both numbers down. Common mistake: measuring over thick clothing or at the wrong spot. Always measure against bare skin or thin underwear.
- Compare your measurements to the size chart: Find the ChiChi size chart online. Match your waist and hip measurements to the closest row. If your waist fits one size and your hips fit another, always go by the larger measurement. The waistband is designed to be snug but not tight. Choosing the smaller size may cause the waistband to roll or feel restrictive.
- Consider your preferred fit: If you prefer a more relaxed fit or are between sizes, size up. The modal fabric has natural stretch, so a slightly larger size still feels secure and smooth. If you want maximum sculpting, stick with your exact size. The thick waistband provides hold without digging in when the size is right. Sizing up reduces compression but still offers a smooth look under clothes.
- Check the colour and size combination: The ChiChi Modal Brief 4 Pack is available in multiple sizes and colours. Make sure you select the right size option before adding to cart, as colour availability may vary by size. Double-check your size selection in the dropdown menu. Some colours may sell out in popular sizes, so order early if you have a preferred shade.
