Going for as little metal as possible is always best, but I do have two few belt buckles in my costume, and they don't cause me any RP discomfort. Though I also make a distinct effort to carry as little coin as possible, and what coin I do have is wrapped in a small leather pouch inside a bigger pouch, so as to conceal it as much as possible.
As far as I've seen, the amount that metal bothers you can also be an IG RP decision. I know there are certain dryads who did not awaken very peacefully, and are thus given bad headaches when even close to metal... but perhaps if you are young, or had a very peaceful awakening, you can touch a coin for a moment and feel a dull burn and get only a slight headache. If I touch a coin, I get a sharp pain... but I don't get a headache unless I do something like accidentally hug someone wearing chain mail. I think the variety of interpretation makes for fun RP
As far as the general look of that - I'd say it is certainly an awesome base for a dryad costume, but as you said, do add some more "fake" vines/leaves that would serve as real leaves IG. If I saw you wearing that in-game, I would would probably interpret it as leather armor crafted in the shape of a leaf (because you love the forest, rightfully!), but I wouldn't think it was an actual leafy part of you. Similarly, I wear a leafy top that (IG) I consider an article of clothing that was crafted from leaves, but I also have leaves in my hair and vines on my arms that I consider to be naturally growing from me.
Hope that helps!
Also, if I am assuming correctly, you are a new player this season? And you look to be playing a dryad??
Can't wait to meet you!!
