Horses are measured in hands and 1 hand is 4 inches. A horse must be at least 14.3 hands. Anything smaller is considered a pony. Miniature horses also exist.

For in-hand showing I would suggest black riding jeans with a "show shirt" that also accents your horses coloring. If you wear a hat make sure that it matches the outfit. during the winter time if you show then, I would suggest some dark colors that will still "pop" the horses coloring so the judges see that you took the time in making your horse look good.
You may stow your gear in the forward hold, sailor! I want to hold your hand. I would be very pleased if you would hold my hand. Get a better hold on those horses, mister!

Horses are measured in hands. They are measured from the ground up to their withers(the crest at the base of the neck). A hand equals 4 inches or about 10cm. Horses are measured in hands because back when everyone owned horses the quickest way to measure horses was with their hands. Approximately, the width of most peoples hands are 4 inches so they didn't have to worry about people with bigger or smaller hands than others.
