Mystique or at least Melisandra

[Falcii]

I'm looking for a way to conceal my characters age long term. I need her to be quite aged for stat reasons but having her be vain and youth obsessed suits her character much more. Is there a relatively cheap way to give the ability to change her appearance at will? Or at least to get one that suits her rather than old lady face. (Items preferred, prcs and feats are kindof starved)

Hat of Disguise (possibly reslotted for the neck slot)?

Could go Druid, which gets timeless body

Even without getting to that level, I think if you get wild shape (through druid, wild shape ranger, wild monk, or divine minion template) and take master of many forms level 1 (humanoid) - that would work too

oops - prestige class starved :) Sorry ...

Hat of disguise is the easiest answer, as above.

I was hoping for something in 1.) A less vital slot (my dm would kill me before a reslot went over) and 2.) that could help shore up the negative effects of aging.

Pathfinder has Youthful Appearance (http://www.d20pfsrd.com/magic/all-spells/y/youthful-appearance) (for looks) and Age Resistance (http://www.d20pfsrd.com/magic/all-spells/a/age-resistance) (for stats.) Notably, both are Witch spells.

So, you want the benefits of age without the downsides? I'd throw the book at you too. :)

Along with the hat and spells that Psyren mentioned, Pathfinder also has Threefold Aspect (http://paizo.com/pathfinderRPG/prd/advancedPlayersGuide/spells/threefoldAspect.html) (Witch, again), that may do what you require.

If you have a feat available - there is the Wedded to History (Dragon Magazine) that can be used, with DM agreement, to give you the ageless trait

There's also the whole mundane makeup option

[Gildedragon]

There's the Kissed by The Ages spell

[Inevitability]

Be a changeling, perhaps?

Also, you could create a custom item of Disguise Self fitted to a slot you like.

[Willie the Duck]

What are your constraints? Do you already have your race/class selected? If not, there's a well known kobold build which gains the benefits of age without the penalties. Likewise, any illusionist-type in the world can fix the appearance issue.

No, I don't think there's anything printed that is exactly like the hat of disguise except a different slot. That doesn't sound like the kind of thing they would waste page space on (even in a splat). Can you tell us which slots you have open?

There's the Gray Portrait from Champions of Ruin. (Take-off on the Picture of Dorian Gray). Unfortunately it's an Artifact.

Unfortunately? You can just grab it from a spell component pouch now!

Elam could also work if race isn't locked down
