Giulietta designer Sofia Sizzi is an undeniable romantic, and for Fall she took that idea in a fairy-tale direction. "This is the story of a girl who enters the forest in a collegiate, innocent wardrobe and, as nature creeps up, she becomes darker, and just a little dangerous," said the designer backstage before the show, sporting a newly shorn blunt bob.

The look played to Sizzi's love of 1960s film and its stars, including Catherine Deneuve, Sophia Loren, and Monica Vitti. A midi-length emerald-green skirt was paired with a feminine placket-front blouse, which was worn under a jacket in a floral-on-black print that popped up again and again. Culotte jumpsuits—Sizzi canít get enough of culottes—were tailored to look like dresses. (The dark-blue version, with olive panels at the waist, was a standout.) And a berry-color day dress with allover pleating showed off some of the techniques Sizzi and her team are capable of executing.

Sizzi worked for some of the biggest brands in the world—including Gucci, Calvin Klein, and Donna Karan—for a good decade before launching her own collection. That time was obviously well spent, as it seems to have allowed her to form an opinion about fashion with which she can confidently stick. Her tailored jumpsuits, for instance, are becoming sort of a signature—a lot of designers this season are talking about dressed-up daywear, and Sizzi is actually delivering polished pieces with a nod to the past, but not too long of a nod. (Her fitted, feminine suiting is a great example of this.) "I'm in love with this collection," Sizzi said. A woman who seeks elegant, modern pieces when adding to her closet might find herself feeling the same.
