Jessamyn's Regency Costume Companion: Your Costume
Visitors periodically ask me where to find a site just like this one, but for another era. There are plenty of great sites about every period of costume, but the ones listed below are great overview/how-to hubs and excellent starting places for both beginners and more advanced costumers alike.
Medieval (pre-16th century)
Kass McGann's focus is on authenticity and do-ability - an encouraging combination. Browse through the other eras on her site, too.
La Couturiere Parisienne
Although this site now offers information on a variety of era, it seemed to begin as a love affair with Rococo fashions and offers some of its best coverage in that area. You'll find lots of images and scalable period patterns.
Fairly comprehensive overview of this much-overlooked period, though no how-tos.
