Yes this would look fine
what do ballets ware? seriously? I'm just assuming that you mean ballerinas and wear. Ballerina's usually wear a black leotard, pink tights, hair in a bun, and a skirt (optional)
It depends on the skirt
Yes you can wear tights with Skirts - Im male and wearing tights and mini skirt that very cool as still as unisex clothes... no law agaisnt men wear skirt or dress or tights as it still allow to wear - feel free to wear what you like
It really depends on what the skirt looks like and if it has a patter or not. If the skirt is plain you can wear black tights and a shirt that goes with that outfit. Pretty much anything can go together as long as you know how to play it off.
You dont?
Leotard, tights, ballet flats, and pins for a hair bun.
Sure, lots do.
blue flats
A suit, maybe with a business like skirt.
It needs to be about spring
Black or Dark Blue
If the lace tights are black I thing you should perk up with a red skirt and a graphic tee. For shoes you should wear white converse or heels.
