Thank you everyone that answered!
Any chaps will do for lower level shows but leathers are needed for higher level shows
I recommend leather, for higher end shows
It really depends on the competition. For a simple schooling show I’m sure suede half chaps are fine. For some higher end shows, leather are suggested. Depending on the type of show you’ll be competing at, tall boots may be your best option. However, different locations have different rules and I would recommend asking your training or checking the show regulations.
