Maternity Clothes?

I’m a bigger girl, I wore XL before I got pregnant and now that I’m starting to show I’m beginning to become insecure about the way my clothes fit. I hate tight fitting clothes and almost all my shirts are too small now. When it comes to pants the only thing that fits me are my leggings and they’re beginning to be tight around my waist as well. I hate maternity jeans and almost all the maternity shirts I’ve bought are becoming too small or don’t fit right. Where do you ladies find nice maternity clothes that actually fit? I’m about to just pick up some men’s 3xl shirts from Walmart and live in those. I’ll even wear moo moos at this point. 😂
