There are sales on everywhere at the moment, you should be able to get one cheap enough. Have you checked online:
Check out this one from riverisland.co.uk – http://www.riverisland.com/women/sale/d … ess-639219
Lovely embellishment and covers up post baby tummy. All it needs is some high shoes, a clutch and some sparkly jewellery. And its available in a 14.

I’d say have a look online, River Island has some fab frocks for 12-15 pounds.
Happy shopping 😀
