Maternity Clothes Suggestions?

LCLaw3

So my family planned a vacation to Mexico in the beginning of January and of course its the middle of winter here and I can barely find any summer maternity clothes.  Specifically, I have a real problem finding shorts or capris to wear while I'm there.  I was lucky enough to find a bathing suit at a Pea in the Pod, but I was looking to get summery pajamas and any kind of bottoms, but cannot find them ANYWHERE.  I know Pea in the Pod and Motherhood Maternity sells some stuff online, but I dont want to pay upwards of $200 for a pair of jean shorts. 

I was wondering if anyone had any luck finding summery clothes in winter and where they got them? or any other suggestions? (by the way...the belly band and I just dont get along...totally uncomfortable for me).  I've also tried ebay and consignment stores, but the places around here seem to have maternity clothes from 100 years ago...and not a huge selection.
