Sometimes we find ourselves justifying certain purchases with the phrase “it’s an investment.” It can be something small, like a watch, or something much bigger, like a house (which, depending on the land, can indeed be an investment). This logic appears across almost every corner of the capitalist world, fashion included. Who hasn’t swiped their card on Masaryk, convincing themselves that this particular coat will only increase in value a few years down the line?

If you’re one of those people who applied this very specific strategy when buying—say—a Hermès Birkin bag, let me tell you: you hit the jackpot. According to a report by Rebag, the most coveted accessory in the luxury world has appreciated by 92 percent on the resale market over the past decade, surpassing its retail price increase, which stood at just 43 percent.

In fact, the same Rebag analysis positions Hermès as the brand with the highest value retention on the resale market (138 percent), a metric that, according to the Clair Report 2025, is reinforced by the brand’s restrictive purchasing policies (you know how supply and demand works): clients are limited to buying just two bags per year. If you want more, you’ll have to turn to pre-loved platforms or resellers. Bags like the Kelly Mini II, for example, have exceeded their retail price by more than 182 percent on the secondary market.

The Row, Louis Vuitton, Rolex, and Van Cleef & Arpels were, to name a few, other brands that stood out in Rebag’s 2025 report—an analysis that examines sales across all categories over the past 12 months.

So yes, it might be time to make a few… investments this Christmas. What will it be? A Picotin, or perhaps a Médor?
