Forget Christmas, it's the Boxing Day sales that make this the most wonderful time of the year... Because when you're stuffed with turkey and sick of arguing over board games with your extended family, what do you do? A spot of internet shopping, obvs.

OK, so we know that Black Friday was literally last month, but retailers still have a lot left to give. It's the perfect time to buy any last min Xmas gifts for people you forgot (dw, we're not judging). Perhaps even some sparkly knitwear for a low-key New Year's Eve or a full-on NYE party dress. In fact, Boxing Day is the one time of year where a lack of organisation is actually rewarded: keen beans will defs have paid more.

Or not – some of the sales have actually already started. Get the low-down in our guide to the best Boxing Day fashion deals:

When is Boxing Day?

Boxing Day is always on December 26, the day after Christmas. It's also a bank holiday in the UK, which is pretty fun.

Is Boxing Day better than Black Friday?

Honestly, it depends on what you're looking for. While Black Friday tends to be the time to bag blanket discounts, Boxing Day is traditionally a clearance kinda sale. In short, you'll get bigger discounts on December 26 (up to 80%) but you'll need to work a little harder – and sizes/stock will sell out a LOT faster. It's not all old season, FYI, most retailers' coats, boots and winter clothes are being reduced right now and, last time we checked, it was still cold AF outside.
