So my boyfriends (3 months officially 7 of being exclusive) parents/grandparents invited me to their Easter celebration! They’re catholic and I’m the lest religions person! I know absolutely nothing about eastern other than candy and the Easter bunny! Can I get a quick rundown of what it’s like also is this outfit appropriate? I’ll be wearing the same skirt and the same shirt but in pastel yellow and pastel yellow open toe heals
