Research suggestions for 16th-century English middle class clothing

nuranar recently contacted me to ask me for research suggestions/inspiration for a friend of hers that is interested in starting to make historically accurate clothing for a middle class woman in Elizabethan England. I asked Ginger if she minded me asking my friends list, since so many of you do make 16th-century clothing for middle-class people in England and are way better at it and more well-informed than I am. And she said yes! So . . .

Dear LJ brain trust,

What books, websites and dress diaries/blogs do you recommend to a beginner who is interested in creating historically accurate clothing for middle class people in Elizabethan England? I believe I'm correct in thinking that nuranar's friend already has some sewing experience, perhaps considerable. If you do other eras or geographic areas, please feel free to weigh in with research strategies!

What I've recommended is under the cut. I've added and refined my earlier suggestions, nuranar!

Anybody else have any suggestions? I'm sure I'm forgetting lots of things I should have in there! I am trying to stay away from modern sewing pattern suggestions, since those aren't actually as helpful as texts/websites if you're trying to do research yourself.
