"A great alternative to a traditional button down, the Nell Shirt is classic with a modern twist. Minimal shaping makes it easy to fit, yet the front placket and strategically placed gathers makes it very flattering. The unconventional collar has interfacing in the back lining so it can be worn standing up for a sophisticated silhouette, or folded down for a more casual look. Make Nell out of shirting, linen or garment weight wool for a daytime or office staple; or sew it up from double gauze, washed silk or voile for a weekend or date night look."
