The longest time difference I've seen between plates is 4 years. I have a Godey's 1874 plate that's taken from an 1870 Le Monde Elegant plate. The 1870 plate is in The Cut of Women's Clothes. I was rather surprised to see a familiar dress when I was looking through it
Anyway, here's the picture:
I also have a January 1829 La Belle Assemblee and Ladies' Monthly Museum that has a copied dress. I have a page for it here
I have the full magazine for the Ladies' Monthly Museum, and just the plate for La Belle Assemblee. They arrived in the mail on the same day. I was rather excited to find the copied plate!
That dress is also sketched in Costume in Detail...
I also have a January 1863 Godey's with a winter hood that also appeared in the Englishwoman's Domestic Magazine in 1863. Unfortunately, I lost the EDM auction
