Do you know "Art of Manliness" ?
It's a website about culture, manly subject and men's lifestyle in general. There's a few interesting topics regarding "old fashioned" clothing. For instance, I remember an entire article dedicated to "how to wear a white T-shirt" (implied like James Dean, not like a random guy in the street) lol.
It also draws directions to the basics to own if you don't really care about stylish stupid trends from modern fashion magazines, but still want to look decent. It's been a while since I didn't read it though. I hope they didn't changed their general philosophy into a more mercantile one.
I don't know if that can help. It helped me when I had to wear a shirt the correct way for a serious interview.
