It looks like basic halfling armor tailoring has vanilla ingredients. Their bags require platinum thread which in turn requires celestial essences. Erudite tailoring looks complicated compared to the other 'classic' cultural smithing/tailoring and also makes use of CE's.

Someone who knows about tinkering can say if those items look classic.


Tailoring

Halfling:
Vale Studded (Non-Imbued)
Imbued Vale Studded (Imbued Plains Pebble - Karana)
Vale Reinforced (Non-Imbued)
Imbued Vale Reinforced (Imbued Plains Pebble - Karana)
***The halfling bags require special threads that themselves require Celestial Essences, so I think they came later. (anyone know when Celestial Essences were introduced?)


Erudites:
Erudite Tailoring requires CE's as well as Vials of Purified Mana which I think come later (when? anyone?).

Tinkering

Gnomes:
I don't know anything about tinkering but if these items are in game it shouldn't be a far stretch to think the Tinkered armors were "classic cultural era"
