Where to buy Maternity clothes?!

Taylor • 22. 2 Cats & Ollie 💜
I'm looking for a nice pair of black stretchy skinny jeans/jeggigs and also a pair of black dressy pants or slacks. I'm in the Dallas area so I have a lot of shopping options but I don't know where to start! I'll be 21 weeks on Monday so preferably something I could wear for most or the rest of y pregnancy.
