Besuited means wearing a suit, typically referring to someone who is dressed formally in a tailored outfit that includes a jacket and trousers.
He looked very professional in his besuited appearance at the meeting.
Besuited → It is formed from the prefix "be-" (meaning to cause to be or to make) and the root "suit" (from Old French *suite*, meaning a set of clothes or attire). The word "besuited" means to be dressed in a suit or to be made to wear a suit.
Think of being 'made to wear' ('be-') a 'set of clothes' ('suit') — that's why besuited means dressed in a suit.
