As many have said, all the trousers are too long, you want a clean line down to the shoe with one shallow break (or none, according to taste), rather than dozens of folds all over the place.
I suppose the suit is RTW, so it's never going to be perfect and compromises are made for the best overall fir possible. The Slim-fit grey suit looks good. Match your tie width to the lapel width and I prefer a dark blue with a grey suit. I often wear blue shirts to weddings to remove the office wear look (which everyone is bound to have).
The long black suit suits you least, it buttons quite high and looks a bit '90s and boxy; no waist suppression. Apart from that none of the jackets are long, why people say things that are clearly not true is a real enigma.
