This isn't a simple case of having the right job leveled. In addition, you need several other jobs leveled alongside it, namely botanist and miner. The ingredients required to craft it need to be earned through a process called Aetherial Reduction. This involves collecting items as if they were collectables from Ephemeral nodes and reducing them down carefully to their base components, similar to desynthesis but more involved. Once done there's a chance you'll get the item needed for your craft.
The Bustier needs Dawnbourne Aethersand. It also needs Aurum Regis nuggets, which are made by goldsmiths using Aurum Regis sand.
That being said, it's BECAUSE it requires so much that it's so expensive and so coveted. Sometimes it's nice to 'sing for your supper' as it were, and have really nice items which are set aside from the crowds. If it was easily available, then it would cease to be as special because everyone would have it.
