Hello style gurus...
I have a ball (military) to attend this Christmas & need a knock out dress... I don't really want to spend more than £140 if I can help it as I won't get much use out of it.
I am used to going to these shindigs but the last 3 years has been wall to wall cocktail parties (no balls at all) so I got rid of my gowns & have also dropped a couple of dress sizes.
I am 5'2" with an hourglass figure and fairly big boobs/hips. And chubby upper arms. Sound delightful don't it?!
I'm a 12-14 in most sizes.
I am happy to buy or hire but quite like the idea of hiring as it means I don't have to cart it there/back on a plane I r eBay it afterwards. The ball is in the UK.
Please can anyone recommend anywhere decent please? It must be floor length & cannot be a cocktail dress. 
Thank you!
