Clothes?!

Rachael
Hey everyone
I am struggling with what to wear everyday. My edema is so bad at the bottom of my bump that I feel like my pants can only come up to the middle of my pelvis in order to be comfortable! I am 34.5 weeks but measuring 46 weeks... I have grown out of all my maternity shirts so nothing even covers my whole belly anymore. 
Any recommendations? My MIL is throwing a baby shower for me tomorrow (not super excited) and at this point I might show up naked.
