Going to Amsterdam for my upcoming 40th birthday with husband and friends, very excited! The main night will be a meal & drinks and I am humming & hawing about what to wear! Never been to Amsterdam but I get the impression its more laid back than dressy ( so am I) plus I have the added pressure of having to pack lightly!! Want to look hip in a 40 year old way if that makes sense? I'm size 14\16, slightly rounded tummy area. Thanks.
