I must say I'm envious of your clothes size! I'm currently 11st 9lbs and in size 14 clothes and I'm only an inch shorter than you Oh to be a size 10...lol.
I didn't expect to achieve a 12 - it was a bit of a surprise, and I'm also at the sad moment where my first size 14 purchase is going on eBay as it's a bit too big now! It's still so damn new...
