Find out if they make you wear a hakama.
Seriously, the Brazilians jettisoned a lot of stuff from the original Japanese schools to get down to business. I'm old enough to miss some of the ritual... it was nice to "make a space" and leave the world outside while tying on the belt.
On the other hand, spending half a class learning how to tie a belt around a gi is a waste of training time. Would a fitness place try to sell you a uniform? Probably not. A uniform with a skirt? No way!
