Costume help?

[stillsostrange]

I need a military uniform for this year's Halloween parade, preferably WWII era (though older is good too). A Red Cross nurse's uniform would also be great. (This is what I really want.) My initial googling has yielded a whole lot of skimpy cheesecake costumes, and rentals from places that don't help me, like Seattle and the UK. Does anyone know a place that sells decent historical costumes for decent prices, and will ship to Texas?

I have army surplus stores in town I can hit up, but they are far and the internet is near.
