When it’s cold it is no brainer to match and wear some stylish bags, coats, suits, shirts (it goes without saying your shirt is tucked in in this case), trousers, and shoes. However as soon as hot weather starts many people find it pretty hard to wear their shirts tucked in. That is the reason they spring for some casual clothes. I just can’t comprehend though how to match some fancy bag and coat (it might be pretty cold in the mornings even in summers) with the casual shirt which is not tucked in and jeans (it would be ridiculous to wear a non tucked in shirt with the trousers). If you are a software developer working in Google you probably could not care less. On the other hand, if you are some sort of auditor working in KPMG you have to forget about casual clothes. The question is how do you manage to look stylish on streets when it is hot.
