Found a relatively easy to understand and use website with good information about Roman clothing that I thought I'd pass along. https://sites.google.com/site/therepublicofancrosaireproject/home
It's an SCA related site, with a detailed list of various specific Roman garments, and some basic methods for making them. The stola method they have is for a banded stola, one I haven't created yet. (I'm not sure how attractive it will be if I can't find an extremely thin fabric.)
It's good for garb, and is a decent reference on type of garment, color and basic construction. Be aware that on the color reference chart that colors vary from monitor to monitor. They have some image slide shows to accompany the pages, and a very nice bibliography of resources, though there's no indication of what information comes from what source.
And of course, they have no information on hair styling! The most impressive part of Roman clothing (for women at least!)
