@Lina-chan: Wowwww the concert is that close to you =O? I'm jealous! I hope you have a great time ^^ the Formal Celes sounds really pretty!
@tarinalove: Honestly I only played 5 min of a friend's copy of FFIII but I love Refia's Freelancer outfit as well ^^! I'm not sure where you would find the tunic/dress in that similar style unless you got SUPER lucky at the thrift store. But if you'd like you can probably get a commission done for the dress and add everything else yourself to save on money/time

. I haven't commissioned anything before though, but there are some ads here at the cos.com marketplace, as well as this
VERY helpful thread on reviews so you can look for which commissioners are recommended or not.
If you're looking to make the vest yourself, you can probably find a denim dress at a thrift store, cut it up, and add the details to it
