Rooted in classic men's tailoring, this fully-lined, slim-fit blazer is detailed with notched lapels, flap pockets, and subtle lipped seams. This three-button style is tailored in a medium-weight certified responsibility-sourced wool suiting fabrication from Italy. Informed by his Dutch upbringing and a deep appreciation of architecture, Paris-based fashion designer Lucas Ossendrijver has worked with some of the most influential European fashion houses. He brings his innovative construction techniques to Theory Project-a special collection that expands on Theory's design codes. This fall, Ossendrijver brings another layer of purpose to the collection through functional and thoughtful details.
