Thanksgiving clothes...???

So I'm 20 weeks preggo on thanksgiving day with my 2nd LO and I already feel huge. I just started really showing, but none of my family has seen me yet. I wanna wear something cute that shows off my belly,but also be comfortable. Any suggestions for my quickly growing size?!  

A nice knit or jersey dress over tights?

Sweatpants/Yoga pants and a Tshirt.... That is the only way to dress on the holidays. So you can eat, eat and eat........  

I'll be wearing a pair of comfy cotton capri yoga pants and a tshirt. I'm cooking for 25 people and want to be comfy. It's also 75 degrees in my house (woodstove). I may wear shorts/capri's all winter inside. lol
