Fit & Size Guide
Overall fit:slim, body-skimming. It’s meant to feel snug when zipped.
Your usual size = close fit. Choose your regular Lululemon size if you like a held-in, tailored look over a light tee or tank.
Between sizes? Size up. If you’re on the cusp of two sizes, go with the larger for easier zipping and breathing.
Broader shoulders or fuller bust:size up one for comfort across the chest/upper back—especially if you plan to keep it zipped during activity.
Layering plan: over tanks/tees → true to size; over thicker long sleeves/hoodies → size up one (some prefer two sizes up for a relaxed fit).
Torso & sleeve length: hits at the hip with intentionally long sleeves; thumbholes are designed to extend past the wrist. Petite shoppers may fold the cuffins once; taller shoppers still get full wrist coverage.
Try-on feel: zip it all the way—no pulling at the zipper or shoulder pinch = the right size. If the zipper waves or the shoulders feel tight, go up.
