Sara Haines will tell us. ? Reporter: Fashionistas like hidely Klum, bejonzen and Kate Hudson are jumping for the jumpsuit. Think Cher circa 1975 but updated. All in one look. No thinking required. Put it on and you're done. Reporter: Our own robin Roberts is a huge fan sporting her own look for an occasion.

Is this for people all body types? Just trial and error like finding a pair of jeans. You have to try on a certain number. A super cute romper from topshop, $96. Perfect for date night.
