Let me go a bit deeper and explain how to optimally CHA-SAD in 1pp.
There's a few specific vital resources you need to be aware of. One is of course the DFT Starknife, which is extremely useful for any build that isn't a paladin. Now technically there IS a way to be paladin and have DFT:Starknife, assuming your GM isn't an ass - it involves starting off as CG and taking the DFT, and then alignment shifting into LG and going paladin from there. Still, we should assume that any DFT:S build is not taking paladin levels as well.
Second, we have levels in Skald (or POSSIBLY primalist bloodrager/barbarian, but those are extremely inferior options). Any of these give us access to the coveted Spirit Totem line of rage powers, giving us a large amount of CHA-to-attack/damage. Moreover, both Skald and bloodrager allow us access to the great (both fluffwise and mechanically) spell Biting Words, which inflicts PHYSICALLY PAINFUL BANTER on our enemy that scales with Charisma - multiple shots, as a touch attack on a 1st level spell! Nothing wrong with this at all.
Thirdly, of course, is the various oracle memes. Lunar, Lore and Nature all have their own little versions of it - the difference being that while LL replace Reflex and AC, N replace CMD and AC. Your mileage may vary.
Fourth is the feat Noble Scion. Taking the War option lets you use CHA for initiative instead of DEX, so if you're using one of the oracle options to be able to dump it you should investigate taking that.
Lastly, there's two niche archetype options that fill largely the same space: Scalefist Monk/UMonk and Iroran Paladin, who both get CHA-to-AC in various ways.
Divine Grace from paladin, and to an extent that Mesmerist ability - as well as that feat, nerfed as though it might be - provide save bonuses.
I believe these are the primary tools we have - if I've missed something, tell me before we move on.
