"The Sound Of Music" has some great outfits for guys who wear hosiery. We just need to bring them into fashion for adults. Read the remainder of the blog entry for the links, and my opinions.
Kurt's and Friedrich's outfits are so appealing to me, because they are not baggy, and because those outfits exude a sense of formality.
Also, notice the guys' shoulders in the second photo. Although those outfits are more formal than our casual outfits, they do not have broad shoulders like our modern power suits.
Unfortunately, they do not exude a sense of maturity. Even in that movie, adults did not wear shorts and knee length pants like that. We have a ways to go before we can wear that to formal business situations.
