This article is a mobile-friendly version of the Moleskin Jacket piece I wrote for my sister site, Hooked-on. If you're interested, I'd encourage you to check out the original there as well.
The images here are optimized for mobile with a vertical layout, which can appear quite large on a desktop. If that bothers you, the Hooked-on version may suit you better.

This site, interest, is a rebuild of the content from Hooked-on — originally written in WordPress — restructured in Drupal, with Drupal's features used to build reverse-lookup browsing and article relationships. My hope is that visitors leave with a broader sense of what interest — curiosity — can mean.
American vintage is what most people think of first — M65 field jackets, A-2 leathers, Levi's and Lee denim are familiar even to people with no particular interest in vintage clothing. This time, I'm shifting my focus to Europe, and to French vintage in particular.
Moleskin Jacket
Introducing the French vintage moleskin jacket.
Born as workwear for coal miners, this jacket is made from moleskin — a tough cotton fabric close in weight and feel to denim — with a distinctive sheen and soft hand. The straight A-line silhouette, with no waist suppression, prioritizes ease of movement while giving the jacket a quietly endearing quality.
Mine is a Le Mont St Michel example from the 1930s–40s. Paired with jeans and a white tee alone, it takes on an urban, mode sensibility that recalls Maison Margiela. It works as an outer layer in spring and fall, tied around the waist in summer — a piece that earns its place year-round.
Styling
I usually wear it as an outer layer over blue jeans or slim black jeans with a T-shirt.
Here I'm pairing it with a Levi's 501XX '55 model — the one I keep for wearing with sneakers, given the length — and slim black Dior jeans, another piece of French heritage, just a century apart.
50's 501XX
Worn here with a 1955 Levi's 501XX — paper patch era — with a Wasew pack tee as the inner layer, which is about as close to a modern-day Hanes as you can get. Whether the front buttons are open or closed, the combination works. It brings out the best of both American casual and European vintage.

It has the kind of presence that could pass for a current-season Maison Margiela outer without anyone knowing the difference.

The cut reads as contemporary. You'd never guess it's nearly a hundred years old.
Dior Slimfit Jeans Black
Paired here with Dior's slim-fit black jeans. A hundred years of French fashion, side by side. The moleskin jacket is workwear at its origin, but it was shaped by French clothing culture and tradition — which is exactly why it sits without any awkwardness next to something as contemporary as Dior.

White and black only — the monotone palette pushes the mode tone hard.

The silhouette from the back holds together cleanly.

Taking the inner layer to black so the whole look reads black-on-black amplifies Dior's minimalist quality and pushes the mode tone further.

Conclude.
This time I've introduced one of the staples of European vintage — the French work jacket. My foundation is American vintage, but pairing it with European pieces brings out something urban and mode that I find genuinely engaging. It's why I keep coming back to it.
Like denim, it began as workwear — and the quiet functionality of the thing, refined over time, is what makes it compelling. Contemporary designers keep returning to it as a reference point for exactly that reason.
Purchasing Store.
The French moleskin jacket I've described here came from Post78.
Post78 is a shop run by an owner with a deep love for clothing — the kind of place that stocks well-made pieces meant to be worn for years. I shop there regularly, and the conversations with the owner about clothes are as much a draw as the inventory itself. Note: Post78 ships within Japan only.
