Welcome to Subeta! Looks like you've already worked out your HA/wardrobe :) Questing is a great way to come across a great range of items, you can also buy them from NPC shops or shop search! SubetaLodge has a great item database to look things up, and there's also an option to 'view all items on Subeta' (As opposed to only ones you own) so you can play dress up with things you don't have yet :)

sP is pretty easy to earn, so don't fret is some of the prices seem really high.

Welcome to you too :)
