This is more of a question on personal opinions rather than strict yes/no rules for a certain dress code. With a few presentations as well as heavy teaching approaching, I have been musing on what is appropriate or inappropriate and how to mesh the dress code I prefer for presentations with the winter issues in cold and snowy climate (don't like wet pant hems etc.). I am talking science presentations in a medical school environment, which is dressier than normal "science" dress code but more casual than clinical side of things. My general (personal) rule of thumb is no suits but a jacket or a refined cardigan/sweater and no denim are preferred. So I guess this would be an equivalent of a business casual dress code.

My general rule has been to wear black, brown or grey dress pants (boot cuts/trousers) or a knee-length skirt (Halogen seamed skirt) with a blouse/dress shirt/fine-gauge sweater and a jacket in a non-matching color or a merino cardigan or v-neck sweater. In the winter, it is easiest to wear the skirts with knee-length boots (mine are mostly low-heeled and end just below the knee). This seems fine for small-group teaching but I am wondering whether boots and tights would be considered too casual for slightly more formal settings. See, for example, this discussion on Corporette http://corporette.com/2012/01/.....-the-poll/

What are your personal feelings? Would you avoid skirts unless they can be worn with pumps? What about ankle-length boots? (That would mean black tights to go with the black boots I have; so black boots and tights would be worn with a grey or purple skirt).

The other question is how narrow can the pants be before they can be considered "too informal"? This may sound as a strange question but I have always felt that bootcut or slightly wider-leg trousers (sort of traditional suiting styling) are the most appropriate for business-casual or business-formal. I remember Angie did a blog post on straight trousers for business code. http://youlookfab.com/2011/08/.....ss-casual/ What about something like Martin skinny trousers (picture #2 in this blog post http://youlookfab.com/2010/08/.....nt-styles/ )? Would you consider them appropriate for a lecture with a longer top under a jacket? Or are they still too "fashion-forward" for a more formal setting?
