"Investment piece" gets thrown at everything from a £900 coat to a £30 candle. But a true investment piece does something specific: it resists depreciation, and in rare cases appreciates. Here are ten categories that consistently hold value on the secondary market — and where to find or sell them.

The reliable value-holders

  1. Hermès Birkin & Kelly — the gold standard; often resell above retail on Fashionphile and The RealReal.
  2. Chanel Classic Flap — annual retail hikes pull resale up with them.
  3. Louis Vuitton monogram canvas — near-indestructible and perennially in demand.
  4. Rolex & Cartier watches — steel sports Rolexes are among the best stores of value in fashion; trade on Vestiaire Collective and specialist dealers.
  5. Cartier Love & Tank — timeless jewellery and watch lines with deep demand.
  6. Bottega Veneta intrecciato bags — quiet-luxury staple with steady resale.
  7. Goyard totes — limited distribution keeps secondary prices firm.
  8. The RealReal "archival" designer — runway Margiela, Helmut Lang and McQueen hold collector value, best sold via Grailed or Vestiaire Collective.
  9. Burberry & Max Mara outerwear — a classic trench or camel coat barely depreciates in good condition.
  10. Limited sneaker collabs — select Jordan and designer collabs hold or climb on StockX.

What these pieces share

Every item on this list has the same DNA: a heritage brand, restrained and recognisable design, excellent construction, and tight enough supply to keep demand ahead of it. Trend-driven "It" pieces, by contrast, spike and crash — fun to wear, poor to hold.

Buy the box, keep the box

For investment pieces, completeness is value. Original packaging, receipts, authenticity cards, dust bags and warranty papers can add 10–20% at resale. Treat them as part of the asset.
