is it ok to wear a short skirt in public with shorts underneath

I usually never wear skirts nor dresses in public unless I have to for special occasions. However, over the last year I've been experimenting with clothes, and the other day I stumbled across this beautiful hand painted skirt and decided to buy it. When it came in the mail I immediately tried it on. It fit me in the waist, but it was to short on me. When I sat down I could see my undies through the mirror. 😅

I have a pair of shorts for these kind of situations; from when I was a pre-teen and became too tall for my church dresses (but I could still fit into them so I never told my mom). I wore shorts underneath to refrain from exposing myself, and to also keep me from keeping my legs closed lol (I've always sat like a guy). At the time I never thought to think if that was even acceptable to wear shorts underneath my dresses (maybe not in the church's eyes but this skirt is not for church).
