31st. The thing you're obsessed with at the moment!
I actually bought a roll neck sleeveless top for around £8 in Forever21 a few weeks ago and loooove it! I was after one for a while and when it was right in front of me in store, I had to snap it up even if it is a Large. It fits fine but now I want a form fitting one - they are so flattering! Cropped ones are great with anything high waisted, which is basically everything that I own!
I was pondering the American Apparel stripy versions but they come in at a steep £23 - until I found the ASOS versions at a tiny £8! I really like the dark red colour which could be amazing with a dark berry lip, so I'm going to hold tight and hope they have a bank holiday discount deal on - retailers ALWAYS do something over an event or payday *hint hint*.
