Buyer tip

Swimwear sales start in July; buy classic black and navy suits then, and new prints in spring.

Buying in Europe: Italian (IT 38, 40, 42) and French (FR 36, 38, 40) clothing sizes are not the same; IT 40 is about a US 4 and an FR 36. Check each house’s chart, and keep returns in mind when you order from another country.

Luxury prices move in a different rhythm from everyday shopping. The great houses (Chanel, Hermès, Louis Vuitton, Dior, Rolex) raise prices once or twice a year, often in January and in spring, and almost never discount their icons. Seasonal pieces, colors and many shoes, coats and knitwear drop 30–50% in the end-of-season sales in January and from late June. Watches from brands such as Omega, TAG Heuer, Longines and Breitling, and most fragrance, see the best prices around Prime Day and Black Friday. Judge any deal against the usual price we show.
