Measuring Guidelines Finding the right fit in Luon®fabric Luon fabric is designed to have a matte finish, so if there's an underlying sheen that reflects the light, the fit's too snug. To see what the sheen looks like, stretch the Luon fabric width-wise with your hands. A fit that's too snug may restrict your movement. And, let's be real, One-Legged King Pigeon Pose is hard enough to get into on a good day.

Women's Bras Match your bra band (28-42) or clothing size (XXS–XL) with a numeric bra size range (2–14). A larger size will provide a slightly looser band fit. A smaller size will be slightly tighter. You decide what feels best. Conversion Chart

Step 1: Find a Tape Measure We recommend wearing a non-padded non-compression bra for most accurate results and if you're wearing a tank or a tee, it's best to give the tape measure a slight squeeze to get as close to the skin as possible. Step 2: Measure the Underband Place the tape measure just below your bust and wrap around the circumference of your ribcage. Note: It's best to keep the tape measure parallel to the floor while measuring Step 3: Measure Your Cup Size Beginning at the center front of your chest, where the breast tissue begins, measure horizontally over the breast with the tape measure across the widest point, stopping at the outer side body where the breast tissue ends. Note: This measuring technique is to find your sports bra size, not the size of an underwire bra. To measure the cup size from against your chest, press into the center front of your bra with your tape measure before you begin.
CupSize CUP SIZE
UNDERBAND UNDERBAND
Use our guide as a starting point to find the fit that feels best. We recommend trying a few sizes to find what works for you. Here are some tips to help you choose a bra that’s both comfortable and supportive:

Look for a bra with a snug underband. Hot tip: The underband is where the majority of the support comes from because it acts as an anchor point, so it’s essential that it fits close around your rib cage, never loose.

Your cups should fit smoothly over your boobs. If there’s spillage (the cup digging into the tissue), the cup is too tight. If there’s a gap between the top of the cup and your boob, it’s too big.

Straps should feel taut, but not too tight. Too loose and they won’t provide enough support, too tight and they will be uncomfortable.

How to Measure Waist For lettered sizes: Use the waist and hip measurements as a guide to pick the right size for you. For numbered sizes: Our pants fit like your favorite chinos. If you're a 32 in the pants you have at home, you'll likely be a 32 in our pants. Bodies come in all shapes and sizes. Normally we select bottom sizes based off our waist size. Guys with a hockey bum might want to size up to accommodate your hip measurement. Hip Measuring your hip is simple, all you need is a tape measure and a full length mirror (or a friend). Wrap the tape measure around the roundest part of your bum and overlap the tape at the front. Turn to the side in the mirror to ensure that the tape measure is making a straight line parallel to the floor. Now look down and check that number! Length Friends are helpful for this one. Stand with your feet about shoulder-width apart in running shoes. Measure from the very top of your inner leg to the bottom of your inner ankle. Repeat this process on your left leg and average out to achieve your most accurate length. You may want to err on the longer-side—short shorts are a yes, but short pants are a no.
Fit Guidelines Finding the Right Fit If your waist measures 33", you're most likely going to need a size 34 pant. This is because we have designed our pants to sit two to three inches below your natural waist. Looking for a good rule of thumb when it comes to fit? Measure your waist and add an inch. If you think you're in between sizes, ask yourself how you want the pant to fit for the activity you'll be using them for. Hemming If you don't have a lululemon store nearby and need to get your pants hemmed, start with a trusted tailor who can do the same type of double-stitching we've used—this will ensure the integrity of the gear stays intact. Still have questions? Check out our Hemming policies.
