Then all the more reason for you not to 'have fun with it.' Though honestly, brown's totally fine. Just fewer choices for what shirts you can wear to match it.
I'm super short, and my siblings would love to send me on 'What Not to Wear'. That being said, when it comes to professional wear, it's not hard to look sharp if you go with the basics. The more fashion sense you have, the more you can get away with trying a number of things and look good.
Try Ann Taylor. They have a good selection of professional wear, and the bigger stores tend to have a decent petites section. They make it really easy for you to put together a spiffy looking professional outfit. Here's their catalogue for suits.

I go in with the expectation that I'll have to have it tailor'd, but I can usually find stuff there and not need to. I invested in a pant suit outfit that fit me best for my college interviews 12 years ago.
Wore it for all my college interviews, job interviews after college, conferences, AND vet school interviews. It was a really good spend.
