If you're shopping alone but need a second opinion, look no further than the Tweet Mirror.
The mirror, brainchild of Dutch retail services company Nedap, can be used to show shoppers what they look like but also allows them to share their image with their friends on social networks - Facebook and Twitter - as well as email and text in real time. Perfect if you're struggling to make that final decision.
Equipped with a high definition camera, the tweet mirror can take pictures of outfits from multiple angles before you pick which snaps to share with your nearest and dearest (or the whole internet, obviously). You then check for feedback from the privacy of your smartphone.
Westfield London are hosting the mirror in the Go Virtual area of the shopping centre as part of The Big Fashion Wardrobe event (29 March-3 April).
