I think there are many ways to avoid looking secretarial. T-shirts might look killer with it as well as some layering (think camisoles, light shirts and cardigans). Also, the shoes can be very instrumental in killing the "business" look. I'm not quite sure of the texture of this skirt or your personal style but maybe so gloss black patent leather pumps?
I like the way you have it now. I'd avoid adding any sort of blazer to this look because, at least for me, that's a sure-fire way to make it look more business like.
