Yves Saint Laurent men's blazers and suits

Yves Saint Laurent follows French conventions and runs structured, often narrower than contemporary production for the same size. On a pre-owned blazer, what matters most is on the inside: the lining under the arms gives way before the outer fabric, and a lining that has come unstitched can be repaired, whereas fabric made shiny by an iron that was too hot does not come back. Check the shoulder seams, how well the collar holds, and make sure the buttons are original and all match.
