Size Guide
Finding Your Fit
At Sirione, we design with intention—balancing structure, movement, and comfort.
We currently offer U.S. sizes 0–12 and XS–XL, depending on the garment. Use the measurements below to find your best fit.
If you’re unsure which size to select, we’re happy to help. Email hello@sirione.com before placing your order.
How to Measure Yourself
Use a soft measuring tape and measure directly over your undergarments. For the most accurate fit, keep the tape comfortably close to the body without pulling it tight.
- Bust — Measure around the fullest part of your bust, keeping the tape level and parallel to the floor.
- Waist — Measure around your natural waistline, typically the narrowest part of your torso.
- Hips — Measure around the fullest part of your hips, keeping the tape level.
