Lounge clothes?

Does anyone have comfortable lounge clothes that you love? I’m currently almost 12 weeks and not showing, but I can’t stand having anything remotely tight around my tummy right now so I mostly hang out in my underwear at home 😳 Obviously this is a problem for several reasons lol. I used to love my yoga pants, but now they feel too restricting on my sensitive tummy because I’d rather have something that goes under my tummy. Please help me find some comfortable lounge/sleepwear! Also, I’m tall and thin, so something that works for my body type is ideal🤞
