Ul'dah has a shop near the Goldsmith's Guild that sells ilvl 29 accessories, other than that, ARR does not really have a place to buy accessories past that item level, and you'll want to either buy them on the marketboard or unlock Goldsmith to craft them yourself (and Miner to get the raw materials)

and as others have mentioned, catch up on your job quests and get that ilvl 90 left side.
