The new updated player characters are going to release this Tuesday already. Remember once it releases there may be lag if you're on a really full server and of course there will be bugs and glitches as with every new thing.
You'll be updated to the new character version automatically, however you can change the appearance once for free.
I highly recommend checking out the character creator sample to get some ideas on how you want your character to look. And remember that they'll add more options eventually.
