In need of new clothes ::sigh::

It's official. Almost 11 weeks and my work dress pants no longer button without really struggling. For weeks I've said "it's just bloating" but it's time I come to terms with it. Don't get me wrong it's so exciting to know that my little critter is growing quickly but I'm such a cheapskate! So it's time to start thinking about maternity clothes or at least solutions to my growing waist. I've heard target, old navy and gap have reasonably priced things. And I just bought one of those belly bands from Amazon so I can try to get away with keeping my non maternity pants for as long as possible and just keeping them unzipped. Anyone have some tips for finding good and reasonably priced professional looking attire?
