I got this on Netflix because I wanted to see Stephanie Beacham. While she's fine (in a part that felt about 50 years out of date even in 1994 - a French seamstress/talk-to who helps the heroine magically blossom), the overall production, and particularly Andrea Roth, won me over.
On paper, Kim is quite the Mary Sue - not only is she an excellent art student, a supportive sister, and a neophyte who becomes a supermodel via one montage, she also brings blackmailers and criminals to justice singlehandedly, and at one point even helps a woman deliver a baby! Yet Roth manages to make all of this believable, as well as managing to make you believe Kim and her twin sister Karen are different people.
I'm not really a huge Rick Springfield fan as other commenters are, but he and Roth have good chemistry and work well together. They do take some odd camera angles to avoid any actual nudity in their sex scene, but for people who want to see some flesh, the version I watched (presumably the international version) has topless extras.
While it's unfortunate that a talented director like Donna Deitch had to resort to helming material that with a few changes would have likely come out of Warner Brothers circa 1943, she really brings out the best in everyone involved.
Give it a try. You won't be disappointed.
