The saint armor is a common armor sold at the shop in the main palace area. The shopkeeper is the armored guy standing behind a table, near the hallway that leads into the dining and party areas. You can buy it as early as chapter 4, once you can finally move around freely. It's not that spectacular that I recall, as you either have better armor already or can buy better armor from the very same shop.
The walkthrough typically doesn't cover common items, unless there's some significance to it, so that's why it's not listed in the walkthrough. If you're trying for a 100% item collection that can make low end computers crawl and perhaps even crash when you pull up the item menu, then you'll want to be diligent in buying at least 1x of everything you come across. Make sure to check stores periodically too, because many of them update as time goes on.
