I need an outfit for a black tie event and need some help/ inspiration please! It's an evening reception celebrating a religious event (but not a religious ceremony) and I am attending in a work capacity (a client is hosting the event) so I need to look appropriate and respectful as well as glam. I am size 6/8, 5'3, flat as a pancake boob-wise but happy with my arms and no stomach issues. My usual style is slightly tomboyish/gamine but I don't think that will cut it for this event. Budget up to £250 but slightly less preferred as I will need to get shoes (I only own loafers, brogues, trainers and flat boots). I don't usually wear a lot of black, but otherwise flexible re colour. Please can anyone suggest a good place to look or even a lovely frock? So far Ted Baker, Whistles, Cos and Rixo have yielded nothing.
