Where Can I Buy Swimwear and Arena Suits Online in Singapore in 2026?

In Singapore in 2026, the easiest places to buy swimwear online are ZALORA for many brands in one place, Decathlon for lap and water sports swimwear, and Cotton On for casual and kids' swimwear.

The stores at a glance

Each of the three main online options suits a different kind of swimmer. Here is how they compare, with company facts from Wikipedia and Decathlon Singapore's own site at the time of writing:

Store	Best for	Background
ZALORA	Comparing many fashion and sports swim brands in one place	Part of Global Fashion Group, which runs ZALORA in Southeast Asia; the group's first platform launched in 2011
Decathlon	Lap swimwear, goggles, caps and kids' swim gear	French sporting goods retailer founded in 1976, with 1,902 stores in 82 countries and regions; came to Singapore in 2016; its Singapore site lists over 18,000 products across 60 sports
Cotton On	Casual swimwear and kids' swimwear	Australian group; Cotton On Body launched in 2007 and later expanded into swimwear, and Cotton On Kids sells kids' swimwear

Other places Singapore shoppers look for swimwear include brand websites, department stores and sports shops, so the right pick depends on whether you want a racing suit, a family beach set or a quick replacement for school swimming.

Where can I buy swimwear online in Singapore?

Start with the store that matches how you swim: Decathlon for training and lap swimming, ZALORA for choice across brands, and Cotton On for casual pieces and kids. All three sell online in Singapore.

1. For lap swimming and swim lessons. Decathlon is the practical choice for one piece training suits, jammers, goggles and caps, and it is simple to buy a full kit in one order.
2. For style and choice. ZALORA lists many fashion and sports brands in one place, which helps if you want to compare cuts, colours and price ranges side by side.
3. For casual and kids' swimwear. Cotton On Body covers women's swimwear and Cotton On Kids covers children's swimwear, useful for beach trips and staycations.

One habit applies to all three: open ShopBack, tap the store, then check out, so you pay less on the same order.

Swimwear Singapore 2026: what to check before you buy

The right swimsuit depends on chlorine use, fit and how often you swim, so check these before you compare prices.

• Purpose. Training suits are built for frequent pool use. Fashion swimwear is cut for the beach and the poolside.
• Fit and sizing. Use the size guide on the product page and measure yourself. Racing and training suits are often cut closer than fashion pieces.
• Coverage. For school swimming, lessons or modest swimwear, filter by full coverage styles, leggings or long sleeve tops.
• Return terms. Swimwear often has hygiene rules for returns, so read each store's return policy before you buy.

Where can I buy Arena swimwear in Singapore?

Arena swimwear is sold in Singapore through sports and swim retailers and some online fashion and sports stores, so search the brand name on ZALORA and Decathlon and check established swim shops. According to Wikipedia, Arena is an Italian company created in 1973 by Horst Dassler, son of Adidas founder Adolf Dassler, to make competitive swimwear. It was sold to Japan's Descente in 1990, and it sells through subsidiaries, distributors and licensees in over 100 countries.

Because Arena reaches shoppers through distributors and retailers, what you find online changes over time. A simple routine:

1. Search "arena" on ZALORA and Decathlon and note which styles and sizes each lists.
2. Check that the seller is the store itself or an official brand listing, so you get a genuine suit.
3. Compare the same model, not just the same brand, since training and racing suits differ widely.
4. Go through ShopBack before you check out at the store you choose.

Is Arena a good swimwear brand?

Arena is a long established competitive swimwear brand, best known for training and racing suits. Wikipedia notes that it signed Olympic swimmers from its first years, including Mark Spitz and Shane Gould, and that it launched suits such as the Flyback and AquaRacer. That background makes it a common choice for lap swimmers and swim squads. For casual beachwear, a fashion brand may suit you better.

Decathlon vs ZALORA for Arena swimwear: how to compare

Compare the exact model, size and price after ShopBack on each store, because neither is always cheaper. Stock and prices for a given Arena suit change with the season.

• Same model. Match the product name and fabric, not just the colour.
• Delivery and returns. Check each store's delivery fee and return rules for swimwear.
• Price after ShopBack. A store that looks a little dearer can work out cheaper once ShopBack's money back is counted.

ZALORA vs Cotton On swimwear: price comparison

ZALORA and Cotton On suit different needs, so compare them on the type of suit you want rather than on which store is cheaper overall. ZALORA's strength is choice across many brands. Cotton On's strength is its own casual designs through Cotton On Body and Cotton On Kids, with multi-buy bundles that can help families.

The fair way to compare:

1. Pick one type of suit, for example a women's one piece or a kids' rash guard set.
2. Find the closest match on ZALORA and Cotton On.
3. Add delivery costs, then compare the price after ShopBack, not the sticker price.

Swimwear Singapore best deals in 2026

The best swimwear deal is usually the right suit bought in the store's own sale, with ShopBack as the step before you pay.

• Buy before the rush. Sizes are often easier to find a few weeks ahead of school holidays and long weekends than in the days just before them.
• Check the sale section. Look at each store's own sale section before paying full price.
• Codes. No code needed: go through ShopBack before you pay and part of what you spend comes back as Cashback.
• Buy a full kit at once. Goggles, caps and a suit in one order are easier to plan than three small orders.

Why ShopBack is a step before you check out

Open ShopBack, tap the store, then check out. ShopBack lowers the effective price of flights, hotels and online orders after you pay.

1. Open ShopBack Singapore (app or website) and search for ZALORA, Decathlon or Cotton On.
2. Check the rate shown on the store's page.
3. Tap through, add your swimsuit to the cart and pay.
4. The cash shows in your ShopBack account as pending, then confirms later.

Cashback lowers what you actually pay for an order. It comes back as cash, so it works like a discount on the price, not like points or miles.

Your effective price is what you pay minus the cash that comes back to your ShopBack account. The real rate is different for each store and changes often, so check the live rate on the store's ShopBack page before you buy. Go through ShopBack before you pay and the Cashback tracks to your ShopBack account.

Card rewards and ShopBack on a swimwear order

You can usually earn Cashback and your DBS, UOB or OCBC card rewards on the same swimwear purchase.
