Approximate equivalents only. Your CEAN size may differ from your usual size, and that's intentional.

*If your measurements span two sizes, choose the larger size. For products where torso, inseam, or other proportions matter (Onesie, Long Sleeve, Leggings), scroll back up and chat with our fit assistant for a personalized recommendation that factors in all your measurements.

1Use a soft tape measure, not a hard ruler.
2Measure in your underwear, standing naturally.
3Keep the tape snug, but not tight.
How to measure: side view showing torso length, waist, hips, crotch, inseam, and floor; front view showing bust, underbust, waist, and hips.
