How many times have you said to yourself that you'd love the Pretty Women polka dot dress?
I can tell you that similar versions have been around at east once a season for most years since 1990 when the film was released. That's a minimum of 25 years of frocks.
In this day & age of on-line possibilities, that's infinitely higher than 25 seasons of possibilities.
So why are you still asking for it?

Off you go, go get it.
