The hardest thing about photoshopping the images is a lot of times the skin tones don't match, which you can see below. Color correcting is not my forte. Make up and lighting has really changed since the early 90s. More so than the clothing styles I'd say. I really wanted to do Roksanda Ilincic's Resort collection (beautiful!) but I had a really hard time matching skin tones so that it wouldn't look really fake. End result, Fran looks really washed out and the skin tones still don't match. Luckily, Fran favored turtleneck looks and they kind of take care of the whole skin tone matching issue.
