Whatever floats your boat, girl. I'm sure you'll find some cute ones!
Mid-length/ over-the-knees skirts are timeless garments. If you need some inspiration, you can check out Chictopia.
I have this hounds-tooth midi pencil skirt and wore it with suspenders and converses-- fun outfit! The 50s hoop skirt and the A-line midi skirt are also trendy too.
As much as I adore a retro mini skirt once in awhile, I believe you should not wear a skimpy school girl skirt to feed other people's personal fantasy. Wear whatever you're comfortable with.
I'm sorry, but a girl should be able to dress how she likes, and her boyfriend can deal with it.
Believe it or not, girls do not exist just to please the boys around them.
I don't think it matters, really. A boyfriend who judged his girl on what type of skirt she wears would probably be a trash boyfriend, anyway. Clothes aren't always for sexual gratification lmao
