summer is coming up soon so white jeans are a perfect match for the weather; keeps you cool, and paired with a bright and light colored shirt would make it pop.

to answer your questions, no you can definitely wear them; i suggest wearing them and go sockless with your shoes; roll up the cuffs but dont make the cuffs look "perfect" just roll them up and forget about em. you can wear them to both formal, informal, and casual events; just make sure they're paired correctly
