Bumpsuit

Anyone out there tried Bumpsuit? I ordered the "Kate" suit and wondering about sizing. I ordered a medium based on the size chart, but it's definitely tight. I feel like that's kinda the whole point and maybe I'm just not used to wearing form fitting clothing. I think a large may just bunch up in weird spots.

I manage a clothing store, and maternity clothes have been such a struggle for me. There are so many cute leggings out there, but I can't wear leggings to work.

Edit: BTW I'm 19+5 so have a while to go.
