Hi Una --
I think you're going to get the best gut check by going full-on preview (jewelry, shoes) with each. And if you want to post the photos, I'm sure people would be happy to re/vote!
As you said, I like that both have the East + West vibe in different ways.
With leggings, I prefer the blue/black combo due more to color pairing than shape.
Without -- and no worries about length -- I think both have a lot of pros. [I do like that more open neckline of the blue on you, though!]
If you're still torn after trying both as close as you can get to how you'd wear them, then maybe leave the tags on and plan on the red if temps are X and the blue + leggings if temps are Y?
