Apart from the comic printed sweaters, the 3.1 Phillip Lim Pre-Fall 2012 Collection appeared very subtle and conservative, but that is what makes it so versatile.
Lim repeatedly combined sweater material with sheer, giving us DIYers another easy designer inspired project.
Remove the sleeves of a sweater and replace them with the sleeves of a sheer top. Don't remove to much of the sleeve on one of the sides.
This one is interesting, I guess you could cut the bottom and sleeves of the sweater then layer on top of another shirt.
