CALYX and COROLLA category sizing
creating an inclusive framework:
solutionary hats for women and textured hair
rosebloom’s simplified category sizing was developed to be inviting for the hat-curious and the hat-furious. our styles focus on the attributes that have excluded women and people with textured hair from the baseball hat industry and their perfect fit. the CALYX and COROLLA category sizing reflects this focus and shift in perspective.
CALYX
feminine-focused hats for women
designed for the slimmer, unique contours of the female skull structure
offers a more comfortable, secure fit
protects her hair and amplifies her style

COROLLA
hair+ fit hats for textured hair
independently accounts for head size and hair volume in design
incorporates hair protection with inclusive fashion options
for all genders



traditional baseball hat sizing methods rely on taking a single circumference measurement where the hat would be worn comfortably on your head, converting that measurement in centimeters or inches to a numbered size (inches divided by pi or 3.14 is your numbered hat size, incase you thought that math class would never come in handy…. it still doesn’t here), and then further converting that numbered size to an adjustable size, if that is your preference.

well, that seems
like a lot of work
for something that
isn’t made for you
in the first place.


at rosebloom, your comfort is prioritized beyond the headwear. that’s why we’ve made it easy to find your headwear size category with no measuring to get a number that requires a Greek mathematician to calculate with an irrational number to get your hat size, just to get a hat that doesn’t fit you anyway.
and once you have your size category, you can choose your style preferences within your category for a great fit every time – no calculator necessary.
