Our core sizes are girls' sizes 4|5 to 14, but we also offer select designs in adult sizes.

All measurements shown below are the actual dimensions of the garment itself, with width measured one inch below armhole when laid flat. To ensure the right size, simply measure your girl's favorites at home and compare.

Our signature fit is "in-the-middle" of oversized, boxy boys t-shirts with sleeves to the elbow and fitted girls t-shirts with tiny cap sleeves. If your girl prefers oversized styles, you may want to go up a size. We do pre-wash this fabric to minimize shrinkage (although all cotton garments will still shrink some).



Our jerseys are slightly roomier than our regular t-shirts – as jerseys should be! But, true to the Girls Will Be style, they're still not too oversized or boxy. These styles are not pre-washed, so they will shrink a small amount in the first wash, especially the length of the baseball jerseys. If you are on the edge, you may want to size up



Our hoodies have a more traditional unisex fit than our t-shirts (but are still not too boxy). We offer two styles of hoodies with the same length, but slightly different widths. Our lighter weight training hoodies fall at the low end of the width ranges below, while our more traditional, warmer hoodies fall at the high end.


For a limited time, we are offering adult sizes of select training hoodie designs. These adult hoodies have a modern unisex fit (meaning that while they are a unisex fit, they are not overly boxy and wide).


Remember, the "waist" shown below is the actual measurement of the garment itself (not of your child's waist). Keep in mind that our shorts are designed to be not-too-tight, but not-too-baggy, with a length that hits just above the knee.

Cargo Shorts:
An adjustable, internal waistband lets you make the waist smaller than (but not bigger than) the dimensions below. Because the fit is pretty straight through the hips, some girls may want to order a size up.sizecharts-cargo-2021.jpg

Perfect Play Shorts:
The relaxed waist is towards the low end of the range shown below, but then the elastic waistband can stretch up to the higher end of the range. The functional drawstring lets you tighten the waist if you need to make it smaller.

The colors with spandex in the fabric have a little more stretch and will fit a little different than the colors without spandex. If your girl is on the edge between sizes, and you are ordering a pair without spandex, you may want to order a size up.sizecharts-play-2019.jpg

NOTE: the size 8 Perfect Play Shorts in Royal+Blue, Charcoal+Light Gray, and Heather Gray+Teal are running a little small, so you might want to size up.


This exclusive design for this event is printed on youth t-shirts with a modern unisex fit (meaning the body and sleeves are a little slimmer than your old-school unisex tee). The youth fit is quite similar to our own custom-made Girls Will Be t-shirts, although the sizing is different because the t-shirt is made by a different company.



We offer select Girls Will Be designs in adult sizes, in either a unisex fit or with a choice of both unisex and women's fits (click here). Since we can't afford to manufacture our own adult-sized shirts (yet!), we use blank shirts from another company. But that means they don't have the same "in-the-middle" fit as our girls shirts (which we do manufacture ourselves). So if you order a women's fit, please order up a size or two (because they run pretty small).

We really tried to find a women's shirt that did not run so small, but was still high quality, available in our colors, and made in the USA. But we could not find one that met all four criteria. So please use the size chart to make sure you order the right size. For reference, our own girls size 14 shirt has a width of 17-18" and a length of 24 1/2".
