I'm a bridesmaid in the summer in all day event day to night, in a london townhouse. Dress is already purchased navy, Grecian style floor length. We can wear any shoes but ideally silvery and with a heel, I'm good with heels but don't want anything too high, mid heel would be ideal. But ultimately I really want to be able to wear them all day and be comfortable without having to edge into flip flops at 8pm! The dresses are super long so I'll need the height (and I'm only 5ft!).. any thoughts!!!
