As we learned during Fashion Week, there are many shades to the deep side part: some pretty, some less-than-pretty, but striking nonetheless. On the safer, more accessible end of the spectrum, we have BCBG‘s version (far right), which keeps things easy and breezy with some lift at the roots. Then there’s the slightly deeper part with flat texture — as seen at Opening Ceremony (far left) — which is more in the vein of Christian Bale’s character in “American Hustle.” But pretty. Finally, we have the granddaddy of all combovers at Alexander Wang. Its severity worked excellently with Wang’s collection, but to all DIYers, we just say: handle with care.
