Two sweaters...separated by $450...two sleeves...and a few hundred feet of additional wool. In the left corner, Dries van Noten's side-zipped mohair number...in the right, Hope's open-sided vest.

Both offer the dual-purpose neckline...it's a bird, it's a plane...no, wait, it's a turtleneck, it's a shoulder covering collar... and both come in pleasingly autumnal marmalade hues...which do you prefer? Function or whimsy?
