EVIE - Lazy Days Hoodie [Ufo]

So I was rather taken by this adorable hoodie, its greatly designed and the ruffles look realistic on it, but trying the Hourglass demo had me confused, it was un-rigged and also didn't match or contour to any of my shapes like other clothing does.

I thought this was just a demo thing, to stop people wearing just the demo, even though it completely defeats the point of a demo which is figuring out if it fits you or not.

So deciding to take a gamble, I brought this one and... that's... that's the hoodie, an unrigged item... why?

I feel like an dummy for buying this, I will be contacting the seller to see what this is all about, weather there has been a mistake with their uploads or this is the intended product.
