May I ask your opinions on wardrobe selection for interview?

I am interviewing tomorrow afternoon with a local high end B&B near my home and am having trouble choosing an appropriate outfit. I am applying to assist with all facets of the business from the casual end such as cooking/housekeeping to customer service related duties, entertainment, wine hostessing/pouring,special events services, for the upcoming season.

While I wish to show my casual, ‘down to earth side’, I am leaning towards a presentation based more on my classy/elegant/hostessing/and social coordinating skills.

Would you show up in jeans and nice top ready to harvest herbs from the garden or…would you showcase your elegant professional side?

I feel it might be best to go ‘casual classy’ skirt, boots, nice jacket, jewelry, than downgrade mode.
Dressing ‘down’ is easy, but I want them to also see the ‘big’ picture and be able to get a feel for how I’ll fit into the more formal situations.

What’s your opinion?
