Not quite everything. Only the first (armoir-able) set of 45/50 gear and the level 70 gear can be repurchased, plus the level 80 gear being reclaimable from the original NPC, but the second level 50 set has to be traded for "antique gear" tokens from dungeons such as Snowcloak and the level 60 gear has to be bought with Centurio seals.

You can get it all back one way or another, but not all from the Salvager.
