meet the new evolved fit

Our sizing has shifted because it’s essential to us that you focus on your moves and not your clothes. After listening to your feedback, we have created the new evolved fit – a tad shorter in the pant leg and sleeve plus the introduction of a new size 7. Use the size chart to find a fit measured to you. Need more info? Check out our frequently asked questions.

how to measure

Ask a parent or a friend to help you out with these:

height - The vertical distance from the crown of your head to the floor. Stand against a wall without shoes and get someone to mark where the top of your head reaches (no tip-toes). Measure from that point to the floor.

chest - Start by placing a measuring tape around the largest part of your chest. The tape should be flat but not too snug.

waist - Your natural waist lies between your bottom ribs and hip bones. To measure, breathe deeply, relax your stomach and lie the tape measure flat around your waist, allowing for a ¼ inch of slack.

hip - To achieve the most accurate hip measurement, find the widest point of your hips and place the measuring tape around. The hip bone often isn't the widest point - it's one to two inches lower, where your hip is at its fullest.

torso - Start by placing the tape measure from a point on your right shoulder midway between your neck base and your shoulder joint, down your back through your crotch and up over your right chest apex, back to the starting point, avoiding constriction at the crotch.

inseam - the vertical distance from the midpoint of the crotch to the floor, taken while standing and without shoes.


fit guidelines

finding the right fit - Your lounge wear can be more relaxed but make sure your exercise pants and bodysuits are snug - but not too tight. ivivva clothes should fit you like a comfortable second skin. Luon® is designed to have a matte finish so if there is an underlying sheen that reflects the light, this means your pants are too tight and you need to go up a size. On the other hand, if they’re too big they can slip or trip you while you’re flying through your favourite dance or athletic class.

ready to wear - Most ivivva clothes are pre-shrunk to ensure a quality fit the first time and so there are no surprises in the wash. Please don’t buy a size that’s too big assuming it will shrink to fit, because it likely won’t.

free to grow hemming - Depending on your height and activity, pants may need to be hemmed. If there is not an ivivva store near you, find a lululemon store and ask for “child’s hemming”. All ivivva items are specially hemmed with a double turn so when you grow, you can go back to the store and get your pants let down an inch. If there is not a store near you, find a trusted tailor and ensure they take notice of our special fabrics or style of stiches, which are designed with intention for the movement of your item. Be sure to wear the shoes you’d normally wear when trying on your pants and hem to at least to the bottom of the heel.
