Is a miniskirt worn with opaque tights acceptable when visiting Italian churches?

Buona Epifania a tutti!

I tried Googling this but couldn't find a response. I'm aware that shoulders should be covered when entering Italian churches and that hemlines should fall below the knee. I was wondering if it's acceptable to wear a shorter skirt if it's with opaque tights? Would this still be disrespectful?

(Sorry for being and idiot! I'd much rather embarrass myself here than during my trip.)
