I have the original Tudor Roses, and was able to compare it to the new edition. It's not just a reprint. There are several new patterns. The men's patterns have been deleted (no Henry VIII!). Most of the other patterns have been modified. Shaping added, sleeves fitted, patterns shortened, and so on. The text about the Tutors is different, also.
I decided to get the new edition also, since it IS my cup of tea, and I had some discount coupons I could use.
