In a tropical country like Philippines, my marathon apparel basics would include a comfy running shorts and socks to keep those blisters away, dry - fit tops, arm sleeves for heat, visor, sports running watch from citizen watches and sunglasses for hours of running.
Plus, don't forget to put on gracious amount of petroleum jelly on your feet, armpit, panty / brief lines, chest and other areas prone to blisters.
It is best to be smart when you run to make sure that your first marathon shall be as pleasant and comfortable as possible. Best of luck!
