How to Measure like a Pro!
THE BUDDY SYSTEM : It’s always easier and more accurate if someone else takes your measurements, so if you can, grab a friend and have a measuring party!
CIRCUMNAVIGATE : All of these body measurements (except in-seam) are circumferences. So make sure to measure all the way around your body, until the tape meets back up with itself.
ON THE CUSP : If you’re on the border between two sizes, then choose based on the fit you want: order the smaller size for a tighter fit or the larger size for a looser fit. If you’re still growing, we recommend going for the larger size so that you don’t grow out of it a month from now!
UNIQUENESS OF FIT : All Jo&Jax designs are unique, so there may be slight variance in the way each style fits. In particular, their fitted Activewear (leos, unis, bra tops, bike shorts, leggings) are designed to fit your body tightly, whereas most of their To-and-From clothing (jackets, warm-ups, tees, running shorts, etc) is designed to fit a little baggy. You may want to size up or down depending on how tight or loose you like your clothing.
YOUTH vs. ADULT : “Youth” Sizes have a slightly different fit than “Adult” Sizes. Youth-sized garments have a straighter fit through the bust, waist, and hip to accommodate the body shapes of our younger customers. However, all of their 4-Way stretch activewear styles and sizes are designed to accommodate many different body shapes. Adults whose measurements match our Youth sizing should feel comfortable ordering that size; and younger customers should likewise feel comfortable to order from our Adult sizes. Don’t let the names get in the way of ordering the perfect size for you!
