I got one pair of leggings from Destination Maternity. The prices are high but I scored with the lowest price one. I've been using them throughout my entire pregnancy so far and no need to go get another size yet. I got some dresses from Goodwill, and Marshall's has some cute maternity shirts. Just remember, you don't have to spend a lot on these clothes. Because once the baby comes out you're not going to remain the same size. Good luck!
My boyfriends mom got me plus sized maternity clothes from old navy and my mom got some for me from target. F2
I ordered 1x and they fit like a 16/18
I ordered a few pairs online from motherhood and they fit wonderfully.
You can order online for target and return in store if it doesn't fit ... they had some 2xls when I looked . Also stores like motherhood maternity , pea in the pod ect have a much wider variety of sizes . I also got some at khols.
