Oh fgs. Buy whatever earrings you like. It's ridiculous to suggest that little studs might be 'edgy' or that a pair of earrings will make you look dated.
I've been wearing (deliberately) odd earrings for weeks, just because I couldn't decide which ones I wanted to wear. NOBODY CARES. Really... (well, except for some random strangers on the internet, and really, we/they don't count).
