Finding activewear that fits perfectly can transform your workout experience. Too tight and you're distracted; too loose and you're adjusting every five minutes. This guide walks you through how to find your ideal SISQUEEN fit across every product category.
How to Measure Yourself
Before shopping, take three measurements with a soft tape measure:
- Waist: Measure around the narrowest part of your torso, usually 1–2 inches above the belly button.
- Hips: Measure around the fullest part of your hips and seat.
- Inseam: Measure from the crotch seam to the floor along the inside of your leg.
Leggings Sizing
SISQUEEN leggings are designed with a high-rise waistband that sits 2–3 inches above the natural waist. Our SisFlow™ and SisSculpt™ fabrics offer 4-way stretch, so they move with your body without sagging or bagging. As a general rule:
- XS: Waist 24–26", Hip 34–36"
- S: Waist 26–28", Hip 36–38"
- M: Waist 28–30", Hip 38–40"
- L: Waist 30–32", Hip 40–42"
- XL: Waist 32–34", Hip 42–44"
If you're between sizes, size up for a more relaxed fit or size down for a compressive, sculpting feel. SisSculpt™ styles run slightly firmer — size up if you prefer a looser waistband.
Sports Bra Sizing
For sports bras, your band size (underbust circumference) determines stability, while your cup preference determines fill and coverage. SISQUEEN sports bras are designed primarily by band size with light, medium, or full coverage options:
- Light support (yoga, pilates): Choose your true band size for a snug but breathable fit.
- Medium support (cycling, dance, weight training): Size down one band size for extra hold.
- High support (running, HIIT): Use the sister-size method — if your usual size is 34M, try 32L for a tighter band with equivalent cup volume.
Shorts and Skirts
SISQUEEN shorts and skirts follow the same waist/hip sizing as leggings. For biker shorts, the inseam length varies by style — check the product page for exact measurements. Our SisFlow™ Flare Skirt fits true to size with a stretchy waistband, while the Pleated Skirt has a slightly more fitted silhouette and benefits from sizing up if you're between sizes.
Tops and Jackets
SISQUEEN tops are cut with an athletic, close-to-body fit. If you prefer more coverage or a relaxed layering look, size up one. Jackets are designed to layer over a sports bra or tank top, so they follow standard sizing with a slightly relaxed fit through the torso.
Tips for the Best Fit
- Check the product's specific size chart — dimensions can vary between fabric series.
- For SisFlow™ styles, true-to-size is the best starting point.
- For SisSculpt™ compression styles, size up if you want less compression.
- If you're unsure, order two adjacent sizes and return the one that doesn't work — SISQUEEN offers hassle-free returns within 30 days.
Frequently Asked Questions
How do I know if SISQUEEN leggings will fit me?
Take your waist and hip measurements with a soft tape measure and compare against our size chart. SISQUEEN leggings use 4-way stretch fabric, so they accommodate a range within each size. If you're between sizes, size up for comfort or size down for a more compressive fit.
Do SISQUEEN sports bras run true to size?
SISQUEEN sports bras are sized by band (underbust) measurement. For light to medium support styles, choose your true size. For high-support styles, consider sizing down in the band for extra hold. Each product page includes specific measurements.
Do SISQUEEN leggings stretch out over time?
SISQUEEN fabrics are engineered for shape retention. SisFlow™ and SisSculpt™ use high-elastane blends that recover their original shape after each wash and wear. Washing in cold water and air drying helps maintain elasticity over time.
Can I exchange a size if my SISQUEEN order doesn't fit?
Yes. SISQUEEN offers free size exchanges within 30 days of purchase. Items must be unworn, unwashed, and in original condition. Contact our customer care team through the website to initiate an exchange.
Do SISQUEEN sizes run small or large?
SISQUEEN sizes generally run true to size across most styles. SisSculpt™ compression leggings may feel slightly smaller due to the firmer fabric — size up if you want a less compressive feel. SisFlow™ styles fit true to size with a soft, second-skin feel.
