Pleasure driving turnout for a county fair show?

[Grace67]

What would be considered appropriate driver turnout for a pleasure driving class at a local county fair driving show? My gelding is a bay tobiano and I drive a Jerald easy entry with black seat and light oak wood accents, wire wheels. My harness is a leather pleasure harness in black with brass accents. I know I need an apron, brown gloves and a hat and I'd like to put together a simple yet pleasing turnout. The show is in two weeks so my shopping will need to be done online with things that are ready to wear, no time for custom

Any suggestions?

Thanks!
