I went last year for the first time when 6 months pregnant. Great fun.
Hat, straps etc - yes I know the rules, the obvious stuff... Don't want to get it wrong... and I'm not pregnant this time 
This dress - only seeing it online but really like it and it may forgive my curving post baby tummy. I'm tall and a size 10/12, is it appropriate / suitable?
