Elizabethan Portraits

Here's another excellent source for garb information: Tudor & Elizabethan Portraits.  It's fantastic if you hope to reproduce garb from this era of British history

Of course, the focus here is definitely the English.  Also, the information is primarily about nobles — the lower classes can be infuriating to research, because they weren't the ones getting their portraits painted.  But if you look under the 'various portraits' section, you'll find a couple examples of the merchant class along with a smattering of images from areas outside Britain: Italy, Flanders and my personal favourite, Germany.

This is definitely worth a good long look... especially if you're thinking of shelling out big money for an 'Elizabethan' gown and want it to really be authentic.
