I have the dress - help me style it please!

[gingerwench]

A plea to all those who know their accessories as I am hopeless!

Here's the dress
www.johnlewis.com/259249/Product.aspx

I am late 30s, short, fat carrying baby-weight and I have auburn hair.
The event is an evening boat cruise in Scotland (dress code has been set as "posh"). To complicate matters I am breast-feeding. I need a cover-up/shrug, shoes and a handbag.

Please help!

Because it's got 3 shades of blue in it I'd be reluctant to mix in another bold colour - I'd proabable pink accessories the lighter shade of blue in the dress or possibly go with brown / gold accessories. If it's a posh do I think you need heals rather than flats and wedges can work well with maxi's

Thanks yes blue wedges would work well i think and being short I definitely need to avoid flats.
