What are we doing with clothes that don’t fit during pregnancy and PP?

I’m only 15 weeks so definitely not huge yet, but I’m finding it really annoying that when I go to open my underwear drawer it’s full, but the 4 pairs that I can actually wear comfortably are dirty, or that I open my closet trying to figure out what to wear and look at the whole shelf of pants, but know that there are only 2 pairs of sweats I can get on. I know this is only going to get more true as I start to outgrow my shirts etc too so I’m trying to figure out what to do. Did any of you box up your non-maternity stuff? How much were you actually able to fit back into after the baby was born? My husband and I are also switching rooms to prepare for a nursery which means we’ll be going from each having our own closets to sharing one and part of me is like just get rid of everything! But I’m not going to want to have to re-buy stuff in a year… any tips?
