After the youngest Obama, Sasha, wore a (sold out, boo) ASOS unicorn jumper to a basketball game last weekend, the internet went crazy for it and demanded a restock. Look, we all need a little more whim in our lives, so indeed - it'll be back online to buy from 2 December. OK, so it may be, er, seasonally inappropriate, but you never know when something like this will come in handy. (See: always...) 

Keep your eye on the ASOS Twitter feed for more updates.
