Someone said there is never a second chance to make first good impression. This is why consultants should be dressed accordingly. Accordingly to the place and occasion. On the other hand, I can hardly see myself in a suit for 10 000 euro, so probably some market segments are psychologically out of my reach, I will never make any impression on them. I do not like the idea of dressing as an expression of one's personality. Probably for people like me it is better to find an expert who will do the job for us and choose our outfit. I have found such expert who does it for me and I follow her advice. If I am to show my personality it would be rather in what I write, or what and how I speak, and not in dressing in this or that way.
