My first reaction was "of course this is a Una look"--the everyday-get-dressed-in-morning-for-my-life version of UWP, not the I'm-for-fashion UWP version. With a few exceptions, most of us on this forum don't live and work in environments that require us to look knowledgeable about fashion to be credible. Fashion is a part of our lives but not in the same way it would be if we were working in a fashion-related field. To me, it makes sense we reflect and acknowledge this fact in our personal style. And I don't think that makes our style less our own; in fact, I'd argue the exact opposite--it's the "personal" in personal style.
Those of us who work and live in non-fashion environments run the very risk of looking less credible and approachable if we dress for a fantasized version of our style on a daily basis. Lisa's comment about not wanting to be known as "the woman with all the shoes" by her colleagues made me stop and think on how a passion for fashion can all too easily end up becoming our main identifier in the minds of other. An admiring comment is flattering, but when my outfits become the totality of me, I'm running the very real risk of becoming a caricature--and that is an unpleasant thought. My personal style ought to enhance my possibilities in life, not stifle them.
ETA: wow, just realized I wrote an essay here--and you just asked for feedback on an outfit! But Astrid's thread really got me musing about why we think our personal style is "out there" even when we are happy with what we are wearing.
And, yes, I think this outfit is totally Una--no one else could wear those pieces like you do. Those pants are UWP because of what YOU bring to the party. Your personal style turns even the most sedate top or bottom into something edgy and a bit dangerous. That's why you rocked the skirted legging--and turned a potential mini skirt into a fierce butt vest.
