EXCLUSIVE AT MR PORTER. The subtle triangle motif woven into this SAINT LAURENT tuxedo jacket first made its appearance on a [shirt id1110962] from the SS19 collection, and we liked it so much we asked the house to re-imagine it for our exclusive capsule. Tailored in Italy from virgin wool-jacquard, this slim-fitting piece is trimmed with satin at the buttons and peak lapels which, combined with the padded shoulders and full lining, broaden the shoulders and streamline the frame.
