Depop
Want to cop that new Supreme drop but stymied by, well, having a job? Leave overnight queues to teenage hypebeasts and fire up Depop instead, which mixes eBay-style selling with an Instagram-a-like interface that simplifies discovering your new must-buy. Should you then rethink that floral silk bomber, selling on is as easy as snapping a picture.

FAD
The fashion world isn't kind to those without insider knowledge, as anyone who's been side-eyed after saying Zegna with a hard 'G' will know. FAD offers definitions of everything from the stuff you should already know to those you probably don't. So you can quiz your tailor on lapel styles without hearing sniggers from the cutting room.

Mod Man
This clever little app stores shots of everything you have hanging in your wardrobe, so you can ensure that in-store temptation sits pretty with what you've already got.

ShopStyle
Like a digital department store, ShopStyle pulls together pieces from hundreds of retailers, and lets you filter by everything from cut to pattern to price. Think Google for your wardrobe.

Stylebook
Photograph the clothes in your wardrobe then pull the pieces together to build outfits, without spending hours in front of the mirror. You can save your favourites, set specific outfits for specific dates (so you know you need that blue Brooks Brothers button-down clean for your cousin's wedding) and even see which you've worn most often. Handy for proving cost-per-wear to your other half.

Chicfeed
Stuck in a sartorial rut? Chicfeed collates street style shots from big blogs like The Sartorialist and LookBook, serving a dose of inspiration to your pocket. It's predictably womenswear heavy, but rest assured, the guy stuff is in there. You'll just have to scroll through a few more shots of beautiful, impeccably dressed women first.

Men's Hairstyles
It's all well and good heading to your barbers clutching a tear-out of David Beckham's new Belstaff campaign, but without his cheekbones, that pompadour might not suit. Find out without six weeks of regret with this app, which lets you trial different barnets and facial hair before taking the plunge. Your future Facebook-scrolling self will thank you.
