Now Amazon will let you try on a dress before you buy it

if ThAT dress you snapped up online didn’t fit, organising returns and a refund can be a pain.

But Amazon is set to take the hassle out of fashion shopping – by letting you try on outfits before handing over any cash.

The online giant will ship items to your door in a re-sealable box which shoppers can use to send the items back if they aren’t right. No money is charged to your card if they are all returned. But Amazon is offering discounts of up to 20 per cent if customers keep five or more pieces.

The Prime Wardrobe service means homeowners can effectively turn their home into a shop fitting room – trying out a range of outfits at no cost before deciding which ones to buy.

The concept, which is currently being tested before its launch in the coming months, is the firm’s latest attempt to revolutionise shopping in the UK.

Last week it bought upmarket grocer Whole foods for £10.7billion as it goes head to head with Britain’s major supermarkets. Now it is taking a direct aim at high street fashion stores.

The service will be available to Amazon’s Prime customers who pay £79 a year for free shipping and music streaming services.

Users pick at least three items from the one million available on Amazon fashion including brands such as Calvin Klein, Levi’s and Lacoste. items arrive in a resealable box with a prepaid shipping label and shoppers have seven days to try on all the clothes they have selected.

Those who decide to keep at least three items earn 10 per cent off the purchase price, while hanging on to five or more increases the discount to 20 per cent.

Shipping and returns are all free. Amazon, which is 14 times larger than Tesco, Sainsbury’s and Morrisons combined, says on its website that Wardrobe ‘brings the fitting room to you’. The items covered include shoes, accessories, baby clothes and fashions for men. Analysts said the simplicity of the service – which has one-click ordering – would help make it a success.

Amazon has already beefed up its fashion operation and in April it launched Echo Look, a voice controlled camera that takes a picture or video of users.

The ‘Style Check’ feature uses computer algorithms to give a percentage rating on how good it looks. The service has so far only been launched in the US and costs $200 (£155).
