Along with what Angel said, the preparation work for Halter Showing is where most of the work comes from! It is based on confirmation and breed standards.
I will spend alot of intense time preparing for my halter shows. Generally a couple weeks prior to the show, mine get another body clipping. Along with the clipping and bathing, I also have to "cook" after clipping which is messy and a task in itself. As I start all the preparation, there is still the lead training going on. I have a farrier come out as well to give a nice cut to prepare the hooves. The day before and day of the show is where it gets pretty stressing. Along with a prep bath, a thorough final trimming of the body and ears are done, hooves are painted, whites are treated and the mane gets banded and trimmed. The day of the show, touch ups are done and anything that came out of place is fixed. The show halters are alos oiled a day or two before as well as shined.
Its always amazing to me how much has to be done when its near that time, and there is always something that can be fixed or touched up.
