First off, here's a larger version (click to see):
My observations on the picture:
1) Did they photoshop her wrist cuff? It looks like they just "painted" over her skin to make it look like she was wearing it (to avoid spoilers?).
2) The undershirt definitely looks black to me, but I guess this could be another case of "blue vs gold". It could also be another spoiler avoidance tactic.
3) Her outer top looks grey, and I'm probably totally wrong on this, but it looks like it might actually have a hood attached. Most Jedi robes do have hoods; could she be wearing a sleeveless padawan robe?
4) I love the hair down look. I suspect that what we don't see is a single bun--it would make sense for them to keep one to recall her look from the previous movie. It would be awesome to see a single thin padawan braid on one side, too.
5) Her arm wraps are still there--I suspect they're for more than warmth. I'll bet we see some tattoos, branding, or other injury (not from self-harm, Disney likely wouldn't go there) that she is ashamed of or wants to keep secret.
That's all I've got for now. I know this is a bit off topic (as it's speculation about the film rather than her outfit) but I'm really hoping to see Rey build a saber in E8. What with her being a mechanical engineering genius and all, she'd probably do something really innovative and it would be fun to see a montage of her trial and error process. And we'd have a new saber to add to our prop collection
