Every colour suits a black horse. However, I find really bright colours quite nice.
black trousers
Black shirt, orange tie.
I'd be wary about pairing the grey suit with black-on-black, a combo that I usually favor. Black and green (or grey and green, for that matter) work perfectly well together. Black and grey usually look good with anything, actually. Good Luck!
Black tie should be suitable.
black shirt
Probably black shirt because black looks good with pink. For the tie, maybe dark or light grey with a little darker design? The colour of the suit seems to say that the even might be more happy, light and cheerful? If so, maybe no tie. But grey would be a great colour with the black shirt and pink suit.
