Special Project: Weekend in Prague - day dress & flats?

[SingingSands]

Hello stylish people, bit of advice needed. DH is whisking me off for a weekend in Prague to include dinner on Friday and Saturday nights (posh place on the Saturday!) and a day sightseeing on Saturday and boat trip on Sunday.

I am very excited at the prospect of a child-free weekend with my love, being all cosmopolitan and wandering around in the sunshine, BUT... I have nothing lovely to wear! I've not bought myself much in the last few years, in my head I'm wafting about like Audrey Hepburn but in reality I'm just "mum in jeans". I'm thinking a nice day dress and flats on Saturday and some wide legged trousers on Sunday? Can anyone help turn me from glum to glam? I'd be very appreciative!

I'm 32, 5'4", brunette, slim(ish) size 8-10, small bust, good legs.
