Located in a Soho space with loft-like beams and a floor of expertly rustic wooden planks, sits a boutique perfect for finding well-cut raw denim, layering tops, wool sweaters, and crisp oxfords. At “Atelier de Production et Creation,” you really do feel as if you’re shopping for items that were thoughtfully and artfully created by a European atelier. Devotees flock here and only here to pull off that effortless Parisian look. Critics who frown at its simplicity and neutrality call it “Socialist Japanese” (perhaps because the founder, Jacques Touitou started his fashion career in the 1980s at the Japanese label Kenzo). Everyone in between comes to give their wardrobe a beautiful backbone. One thing is for certain: you won’t find that “look at me” little black dress to go clubbing in at A.P.C. – just simple, well-done basics that master a flawless, minimalist chic.
