I'm going to a dinner at a nice restaurant next week with my future work colleagues (I've just been accepted into a partnership) and I am very unsure about what to wear.
I'm 31, size 16, big boobs, long dark hair. Worried about looking too young and want to look sophisticated and elegant but not too formal 
I think I've over thought this and lost all perspective. Help please!
