Barefoot Dreams OAP says it is "high-end, luxury loungewear".
It does look comfy. And I love the muted colors. Elegant-casual is how I would describe it. Yes, you charge an arm and leg for it. But nylon and poly-rich clothing is not what I would consider high-end. Nothing wrong with nylon. I like it myself (maybe not 78% in a sweater like many of theirs have). But wouldn't feel like I am luxuriating while wearing it. (I realize they also have cotton pieces which look nicely made).
Regarding the Malibu Collection, host Julia C. says: "I know this. I understand it." If you are going to claim the part, then play the part. She seems to make it look more sloppy than loungy. I know she is from Cali, but I don't picture her gazing out of her seaside cottage window, while sipping her chamomile tea, all cozy in her seafoam cardigan. More like waking up with a hangover, smeared mascara, shirt askew, topped with a schmatta.
Posing in her high heel/jogger pant combo, She says, "I get stopped all the time. Well, I'm not that cool. But people ask me..." I would have hoped her host mentor would have told her to never have an inner dialogue out loud. If you are going to create a false scenario, commit to it. Otherwise, you look like you are making it up as you go along.
