Hi. The main difference for me is that there's no such thing as "suit with"! However, you could say "He is well suited with you", when you're talking about match making. 做媒人时：他配得上你。 "Suit" is more commonly used to talk about clothing. "Does this hat suit my sweater?" 帽子是否跟毛衣相配。

We don't say these but something can be 'suited to your needs' which means changed or altered 'to suit' your requirements.

They don't make sense. Here are the dictionary meanings of "suit" 1. a. A set of matching outer garments, especially one consisting of a coat with trousers or a skirt. b. An outfit for a special activity: a diving suit; a running suit. 2. A group of things used together; a set or collection: a suit of sails; a suit of tools. 3. Games : Any of the four sets of 13 playing cards (clubs, diamonds, hearts, and spades) in a standard deck, the members of which bear the same marks. 4. Attendance required of a vassal at his feudal lord's court or manor. 5. Law A court proceeding to recover a right or claim. 6. The act or an instance of courting a woman; courtship: She was inclined to accept his suit. 7. Slang : One who wears a business suit, especially an executive. Meanings of suited, suiting, suits. 1.
