I wear cotton/spandex breeches, a t-shirt, my helmet, and ankle high riding boots.
The cotton/spandex breeks wick away moisture, and my helmet is vented. My riding boots are the 'athletic shoe' type, and they're very comfortable.
I do have tall boots, but I save them for the hunt field and during colder weather.
NEVER ride wearing regular athletic shoes. They're not made with riding in mind, and can get caught in your stirrups.
If it's too hot for you to ride wearing the correct gear, then you shouldn't be riding at all.
