Suede up 124%, leather up tenfold: Korea's fall outerwear buy is a mix problem

Vince's assortment shows the mix problem the platform numbers hide. It is going to 15 jacket styles this year from eight, and leather and mouton jackets to eight from five ^[11]. That is 87.5% more jackets against 60% more leather ones ^[14][15]. So the leather and mouton share of the jacket range actually falls, from 62.5% to 53.3%, while everything else more than doubles, three styles to seven ^[16][17]. A buyer reading 29CM's 124% suede transaction gain ^[2] as a mandate to load leather would be buying against what one of these brands did with its own open-to-buy.

The two platform figures also do not sit on the same axis. The 124% is measured against the same period a year earlier; the 140% gain in searches for "suede jacket" is measured against the previous week ^[2][3]. Week-on-week search volume in the run-up to Cheoseo ^[1] tracks the weather more than it tracks the season. That leaves two year-on-year lines: the transaction number, and Eleil's leather jackets, which Shinsegae International puts at more than tenfold over the first 20 days, an increase above 900% ^[4][19]. Neither comes with a base, and a tenfold move on a small women's-wear leather program is a different fact from a tenfold move on a core one.

Where the margin sits is decided inside the material rather than by it. Vov has gone both directions at once, adding faux-leather shirts, skirts and short jackets to widen a cheaper range while rolling out natural sheepskin and goatskin suede as premium ^[7]. Della Lana pairs sheepskin with goose down in a single bomber ^[8]. Vanessa Bruno puts nylon alongside leather, suede and fur across its bombers and blousons ^[22]. One trend word on the tag, several cost structures underneath it.

The number with real money already behind it is Isabel Marant's. LF, which distributes the French brand in Korea, raised its fall-winter outerwear buying volume by 188% year on year, concentrated in shearling fur and mouton ^[10]. That stock was committed well before the 12-day window the platform data covers ^[20]. LF's stated read is that the light formal look is moving off lightweight summer fabrics and onto texture: leather, suede, shearling and tweed ^[9].

The more durable signal is category, not fibre. Jill Stuart New York's women's line took standalone jackets to 78% of its offer from 32%, 46 points and roughly 2.4 times ^[12][18], and Eleil pushed past sheepskin jackets and shirt-jackets into leather flare skirts and lambskin pants ^[6]. Shinsegae International attributes the appetite to leather being shown heavily in 2026 fall-winter collections in Paris, Milan, New York and London ^[5]. A less flattering explanation also fits the same data: a jacket sold on its own is a jacket sold at full price, and a leather skirt is the second unit in the same basket.
