I recommend sizing up in lululemon cropped scuba. I typically wear a size 6 or xs/s in sweatshirts and scubas but went with a size 8. Hold tight tank fits true to size (my size 4). Align leggings I recommend sizing down (wearing a size 2). lululemoncreator ad LTKfitness LTKfindsunder100 LTKstyletip
