The buyer: Louis Terline, owner, Oak, New York City

What did you invest in heavily for spring? For us, spring/summer is always about two things: How do you deal with warm weather in the city, and what do you need for the few times you get out of it? This always means easy dresses, skinny jeans, and oversize tops. Sturdy sandals with great style. This season we are enamored with Filippa K. and Nicole Farhi for their casual elegance, Anntian (these great light, hand-printed tops from Berlin), and C-Neeon for their colorful airy dresses and tops. Matt Bernson sandals. High-waisted shorts.

What's been your best seller so far? Our favorite line and best seller BY FAR this season is Complex Geometries—Clayton [Evans] makes the most amazing architectural T-shirts and jersey dresses. We ordered tons of them and are already sold out (a reorder is on the way). The Oak Zebra oversize silk shirtdress was almost gone before it arrived. Luckily we were able to throw some more in.

What are your customers asking for when they come in? It's easy separates that have some style. People are becoming more comfortable with playing with proportions. Things are simultaneously getting looser and tighter. It's a very exciting time.
