Brits work their way through as many as 29 different stages before finally purchasing an item of clothing online, with free delivery, reviews and money off vouchers considered first.
A poll of 2,000 adults revealed the process of finding something you like and then buying it involves an hour and 20 minutes of mulling things over and getting the opinions of two other people.
Shoppers will also watch videos of celebrities or models wearing the items to see how it looks in real life before deciding whether or not to buy something.
And while men are just as thorough with their shopping research, women are twice as likely to screenshot a picture of themselves in an outfit to friends, while one in 10 will send a video of themselves to a girlfriend for approval.
The stats emerged in a study by Brightcove and also found one in six shoppers are more likely to buy something if they can watch a video of it being worn or used.
Mark Blair of Brightcove said: “When we are shopping and parting with our hard-earned money, it can be a long time between seeing something we like and actually deciding to buy it.
“It’s often not as simple as just walking into a shop or going on to a website and buying the first thing you see.
“Technology has changed the way we shop and thanks to video and social media, it’s now easier than ever before to get the opinions of others or see clothes and accessories captured in ways other than the still images we were once used to.
“Video allows us to find out even more about a product before we buy it, meaning we can be completely sure that it is right for us.”
Researchers found the first key stage of buying a new outfit is checking the website in question offers free delivery.
Brits will then go on to surf several other sites before reading relevant reviews.
A savvy 34 per cent of shoppers will then hunt for money-off vouchers, in a bid to save the pennies and bag a bargain.
The fifth most popular stage of shopping involves filling the basket with clothes, with a view to returning later once a decision has been made.
Three in 10 shoppers will continue to compare their in-basket items with other purchases, while 22 per cent will add items to wish-lists and the same percentage will make the effort to go in-store to try clothes on.
Other common shopping stages include adding the same item but in a variation of sizes and colours to the basket, asking colleagues what they think and emailing partners for an opinion.
A fifth of shoppers will even check their bank balance before hitting the ‘buy’ button.
The study also found Brits love to watch a video before making a purchase, and for 18 per cent, a celebrity endorsement immediately makes an item feel more luxurious.
Thirteen per cent expect to see a video of a product before buying it, and 23 per cent claim the production of the video definitely influences their decision to purchase.
