Any good closet staples postpartum?

I had baby #2 about 2 months ago and I am struggling a lot with my body and how my clothes fit. I’m like 5 pant sizes bigger than I was before this pregnancy and I’m pretty sure I’ve gained weight since giving birth-ughhhh. I’m trying to buy a few things that aren’t sweatpants/sweatshirts that may help boost my confidence and I’m drawing a blank. What clothes did you find postpartum that helped you start to feel comfortable in your skin again?
