I've got a trip to the west end planned for next week with the DH, a rare date day/night as DD is at my DMs. I'm looking for something to wear ideally a dress that I can wear comfortably during the day and then suitable for the theatre in the evening. Needs to be cheap as poss as on a tight budget. I'm 5'8, size 16 and not a heel wearer so would need to go with flats. Asking to much?
