What was cool twenty years ago simply isn’t cool today. What was preppy, on the other hand? That’s another story. Just take a look at some well-known preps in recent decades. From Alex P. Keaton to every character in Gossip Girl, they all had very similar styles—with characteristics that would read chic to this day: They lived in oxfords, they wore color with abandon and they never met a cardigan they didn’t like. What’s more, they were true to their look, maintaining a “preppy” vibe from their hair to topsiders. Inspired by these tubular—make that amazing—fashion icons, we decided to compile a guide to getting “preppy” just right. Follow the blog all week long, and you’ll never have to worry about going out of style.
