How to find your personal style again after childbirth?

My personal style changes with the seasons, but as i was fairly underweight when i got pregnant, nearly any of my old clothes fit. And the few that do dont really feel like me anymore. I normally have big, bright, thrift store looks, but ive been trapped in amazon maternity leggings and plan shirts for months now and not sure how to figure out what clothes i want to get anymore. Going to a bunch of thrift stores today to see if theres anything i like, but i feel like the only astetic i have these days is spitup over the shoulder or built in belly band jeans. Idk what my vibe is outside of that and ive never had this issue before
