I like outfit #2 because it looks clean and neat, polished. I like the others a little less because they seem like they've lost their shape, but otherwise I'm a big fan personally of the style.

I think as an alternative health coach, I think you really can wear just about anything. You just want to be clean, neat, and healthy looking... and I suppose that does present a little bit of a problem when it comes to rocker style. A good rocker style look should be slightly unhealthy looking.

Frankly, of course, Lululemon would be the easiest thing to do.
Being asked to remove my shoes has always felt awkward and somewhat rude to me. One time I had on tall boots and had ugly socks on underneath and felt embarrassed. I don't really like the idea of having to wear someone else's slippers either (ewww).
FWIW, I've lost the padding on the bottom of my feet so I find it very painful to go barefoot -- kinda like the Little Mermaid.

For clients' feet, what about this Girl Scout craft: On what you decide will be the bottom of tube socks, take fabric paint and paint dots or other designs. This will make them non-slippery. You will probably need to buy two sizes to accommodate smaller and larger feet. The socks can be washed after a single wear to eliminate the yuck factor.
For what to wear while at work-- I think you have a lot of choices.

But I have a question: is the nature of your job such that people WANT you to present yourself a certain way? IE, if there wasn't an element of the exotic, then you would be seen as not as qualified or presenting the healing experience people are looking for? If that is the case, I'd be careful about becoming too contemporary.

That said, I like outfit 1, and some of the options in outfit 4. I would layer them over skinnies if you are looking to be slightly more contemporary. I do not like the blouse in outfit 5 because it hits you at the widest point on your hip, which is unflattering to my eye. Maybe you could have it shortened a few inches? I might put a couple of loose flowy blouses on your shopping list. It's a more modern silhouette without being too different from your current wardrobe. The other thought I had is that you could look at harem pants or some of the slouchy track pants that Angie posted recently. I think the long ones with the narrow cuff at the bottom could lend an air of the exotic and work well with a structured jacket. Final suggestion/question: how do you feel about Eileen Fisher? Her items are spendy, but she does some of the silhouettes I am describing (for visual reference).
Robin M thanks. I will check out Eileen Fisher & I might end up in those slouchy silk sweatpants sooner than I thought. I'm going to try them anyway. I think if I look for more luxe fabrics & style them the way Angie suggests I won't look like I'm in my sweats or pajamas.
