fashion plate

to dress in styllsh clothes; to look successful, to look well dressed.

Joe's a nice guy, but he's no fashion plate. Just wears jeans, white socks--you know the type.

Fashion plate

It means the latest clothing trend.

Someone is ON a fashion plate.

It means this person dresses in the latest trends or are at least interested in following them up.
