Congratulations!
This may not be the most practical answer but the best solution is to have an expensive suit made of high quality wool, e.g. Super 200. Packing wrinkles from high quality suits will fall out when exposed to a steamy bathroom.
Failing that, I have found a carefully folded suit in the bottom of a suitcase about the same as the "suiter" function. I use the suiter function in my bags "because it's there" and it takes up room but I have found little difference wrinkle wise.
Till?
