Around the office we dress pretty casually. Jeans, comfortable clothes and sometimes even slippers if my feet get tired from standing. When it comes to conferences, meetings, lunches or other business events the good clothes come out as I think they should.
I have a rule that how you dress not only gives people an immediate first impression of who you are, how successful you are, how good your writing is, or how good of an agent you are, but how you dress is also a show of respect. If I have pitch appointments I want to dress in a way that shows the author I respect what she’s saying to me, I think she’s a professional and I’ll treat her as such. Shorts and a t-shirt don’t convey that, at least in my opinion.
As conference season rolls around I know a lot of authors are going to be worrying about what to wear. I don’t think you need to run out and buy anything new, but I do think you need to consider how your choice of clothes might influence another person’s impression of you. Suits aren’t necessary, but looking your Sunday best is probably a good idea.
