I'm 36+2 and i honestly haven't gotten any maternity jeans...i gave up because i couldn't find any that'd fit me. The band part fit fine on my belly, but they'd be sooooo freaking loose on my legs... :/ i've just been using my normal jeans and a belly band.
Old navy sells maternity pants in short I'm 5ft 1in and they are the only one who worked for me
I like old navy they have very cute maternity clothes. Normally name brand clothes will run smaller then the ones from Wal-Mart or target. Although Wal-Mart had some on clearance online that were so cute.
You may want to look at motherhood. They will be a little pricey but they are worth it.
