Help! Fashion fix needed

[olympicsrock]

I need a new dress to go to the Barbury Horse trials in wiltshire next weekend. We will be in the corporate hospitality section with my husband’s colleagues. DH has asked me to get a new dress that is fashionable /summery/ smart. I should be less smart that a wedding . We have been told to wear flat shoes as we will be walking around the racecourse.
I am a size 16-18 with a fairly curvy shape, 5’7’, and a rounded tummy but slimmer waist. I would welcome any suggestions.

Can we have some ideas of what you like? Usually wear? Or any celebrity's who you admire fashion wise?

I like modern prints, assymetric detail. Often wear v necks, ruching around the tummy, fitted waist, jersey. My style is baukjen with monochrome dresses, jeans and tops at home. I am 40 with a 2 year old and I out on 2 stone ( but just lost 10 pounds) but have not bought anything new for ages. Not sure about celebs...
