Arrive in style

Hi,
What does 'arrive in style' mean?
e.g. He arrives in style at the game.
Thanks.

to "arrive in style" is to make an impression on appearing somewhere - it has connotations of luxury or of panache - so somebody "arriving in style" might be well-dressed, look cool and/or be chauffeured by limousine. Alternatively, the person could parachute into the arena.
Providing that the arrival is cool, glamourous or eye-catching in a positive way, you could say the person arived in "style".
"Style" is one of those difficult to define attributes which very much depends on context.
