| Banker-Stripe Boxy Blazer Seoul Collection: Choose this if you want a boxy, relaxed double-breasted blazer with narrow vertical pinstripes on a dark fabric, featuring wide peaked lapels and hidden side slit pockets. The soft stretch fabric (70% polyester, 25% rayon, 5% spandex) with a full satiny lining and slightly dropped shoulders suits a loose, straight-cut silhouette. It comes in Grey and Navy/Midnight Blue but only in small, medium, and large sizes, so it may not fit if you need sizing outside that range.[1,2,3,4] | Banker-Stripe Suit Jacket Wool Weave By Marlane Reykjavik Fit - Semi-Slim: Choose this if you want a double-breasted, banker-stripe suit jacket in Le 31's Reykjavik semi-slim fit, which narrows at the waist with a 7 drop and features wide peaked lapels and a six-button front. It suits shoppers who value an Italian Super 100 pure virgin wool weave by Marzotto with a thin satiny lining, offered in Taupe and Blue in regular sizes from 36-REG to 48-REG, with long sizing (42-LONG, 44-LONG) available only in Taupe.[5,6,7,8,9,10] | Essential Wool-Blend Suit Jacket London Fit - Semi-Slim: Choose this if you want a classic, single-breasted two-button jacket in Le 31's London fit semi-slim cut, with structured shoulders, notch lapels, a welt chest pocket, and flap hip pockets. It works for a traditional dark-navy look in a smooth, matte wool-blend suiting fabric, and the lining is 100% recycled polyester for shoppers who value recycled content. Sizes run from 36 regular through 48 regular with some short and long options, though the exact wool-to-blend ratio is not specified, so check the fabric details if composition matters to you.[11,12,13,14] |
