When is this done and for who ?

Because I saw a developer say you need all 3 pieces AND you have to unlock the costume project before you can edit your outfit.

But is that for your boff's or does it include yourself too ?
I saw a guy in omega with some red on it just last night on tribble (doubt he was t5), so if you have the 3 pieces can you still edit it at tier 0 ?

This has me royally concerned because I'd hate to see everyone looking exactly the same in teh new season :/
