The checklist

  • Fabric: silk, wool crepe and good viscose drape and breathe; heavy polyester feels warm and looks cheaper.
  • Lining: a full lining makes a dress hang better and last longer.
  • Alterations: a dress with seam allowance at the side seams and hem can be tailored; many delicate dresses cannot.

Set your budget

The designer dresses we researched sell for $400 to $25,000 in the US. Decide how often you will wear it first; the most expensive piece is often a skip for everyday life.

Buyer tip

Buy occasion dresses in the end-of-season sales if you can plan ahead; for an event within weeks, check return windows carefully.

Buying in Europe

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.

Before you buy a designer dress: the essentials

Buying a designer dress is easier once you know which details actually change how it looks and lasts, and which are just marketing. This guide covers exactly that, plus the budget to plan for, sizing and buying across the US and Europe, and the pieces we would buy today.

What to spend

The designer dresses we checked sell for $400 to $25,000. Below that range you usually lose materials or make; above it, make sure you are paying for craft and not only the name. Today the Diane von Furstenberg Wrap Dress is the safest buy, and the Diane von Furstenberg Wrap Dress is the most affordable one we would still recommend.

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.

Buy from the fashion house, an authorized retailer or a reseller that authenticates and guarantees every piece, and keep the receipt, the dust bag, the box and any warranty card: they matter for repairs and for resale. Swiss watches carry a 2- to 5-year international warranty when bought from an authorized dealer, and buyers in the EU and UK also have a legal guarantee of at least two years on new goods.
