Since it’s inception a couple of years ago, Fashion’s Night Out (FNO) has become a global multi-day event where retailers can drum up business and the savvy shopper can score a freebie or two. Now, Madrid has over 340 shops signed up to participate, scheduled for Wednesday, September 72011…and this is tomorrow darlings!!

Remember that you have to register to get your invite. Can do it from here.

The basic concept is that fashion brands and shops will stay open late into the evening (often until midnight or beyond) to allow shoppers time to peruse their displays and latest season’s collection.  Often, the shops will have music, free demonstrations or services and special discounts for FNO shoppers.  The perks vary based on the shop, but you can find out all the deals and plot out your approach based on the information Spanish Vogue has posted on their website.

For those who prefer to shop at home or who can’t make it to the events, check out the online deals also on offer.  And if you’re still travelling, check out the other offers worldwide.
