Vintage Lanvin Studio Double Breasted Virgin Wool Pinstripe Suit Jacket Sz 52

This is an incredible vintage Lanvin double button wool suit jacket in pristine, perfect condition. Navy blue wool with herringbone and blue and red vertical striping - very polished and professional menswear look. My knowledge helps me estimate this piece is from the 80s. I believe this may be a bespoke piece because there is no size tag available. Chest across is 21.5in which puts this between a European 52 or 54 for size. Union made in USA from ACTWU. MEASRUEMENTS (buttoned and laid flat): Chest 21.5in ; 43in total Length 30in Sleeves 23.5in In excellent pristine condition. No damage or signs of wear.
