Luxury swimwear

What decides it

Fabric: chlorine-resistant Lycra blends keep shape longer; crinkle fabrics stretch to fit but sag with time. Support: underwire and molded cups help larger busts; triangle tops suit smaller busts. Care: rinse in fresh water after each swim and dry flat in the shade.

The pieces we would buy

Start with the Eres Les Essentiels One-Piece: classic one-piece with lasting fabric. The Eres Duni Bikini is the better buy if you want supportive luxury. Usual prices run from $200 to $700. See the full buy-or-skip list or the head-to-head Eres Les Essentiels One-Piece vs Eres Duni Bikini.

Buying in the US and Europe

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.

Quick answers

Is Eres swimwear worth the price? Its fabrics hold color and shape for years, and the cuts are flattering. If you swim often, yes. How long should a luxury swimsuit last? With rinsing and flat drying, several summers. Chlorine pools shorten the life of any suit.

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.

How we make the call: we read the house’s own product details and care guides, compare materials and construction, follow owners’ long-term experience and track the usual retail and resale prices. A piece gets “Buy” only if we would tell a friend to spend that money on it. No fashion house can pay for a verdict.
