<p>I work in biglaw. Flowerhead, if you want to make a good impression, you’re doing yourself no favors by wearing that polyester suit, even at a place with a business casual dress code. At a client meeting, the client might not notice your polyester suit, but the partner introducing you to the client MIGHT. My advice – take it or leave it as you wish – is to have two decent (wool) suits for the summer, so that it is not noticeable that you have only one. You are getting good advice from sallyawp and TheRoad; you want AVOID being noticed for wearing substandard clothing. Even if the office is business casual, investment in one or two decent (top dollar is not necessary) suits will be worthwhile this summer, and will serve you for some years to come.</p>
