One of my secret weapons for up-leveling a guy's style is to mix in new colors, textures and patterns. With the cold weather upon us, now is an excellent time to do this because there are natural ways to change up your style -- and do it well. Below are some of my best tips for how to do this.How to Turn HeadsTo get the women around you to take a second look, you need to change up how you dress. If others are used to seeing you in solid blue shirts day after day, and you all of a sudden show up in a purple check, it's going to make a real difference. (Now of course, not everyone wants their style upgrade to be immediately noticeable. If that applies to you, go for a subtler change, say a switch to a blue check.) Certain colors, textures and patterns are more seasonably appropriate than others, and that's what I'm going to tell you about today for Fall and Winter clothing. I'll break this down for you into three main categories: color, texture and pattern.ColorFall and Winter is the right time to start incorporating darker, richer colors like olive green, bright red, deep purple, royal blue, chocolate brown and rich navy. Think about these tones for sweaters, pants (like the green AG cords above), shirts and sportcoats. These are the colors we typically associate with cold weather, so it makes sense.TextureThicker, heavier textures like in my client's jacket above are also more appropriate as the weather cools down. These include flannels (for dress pants, suits, sport jackets and also shirts) tweed, corduroy, suede, quilted outerwear and thickly-knit sweaters.PatternsIn these thicker fabrics, Fall and Winter-friendly would patterns include houndstooth, windowpane, glen plaid, and regular plaid.The beauty of cooler weather is that you get to incorporate more layers as the weather cools down, which in turn means more of these colors, patterns and textures can become part of your outfit. And as a result of that, your outfit becomes much more interesting.How do you plan on mixing up your wardrobe this season?Cheers,Julie
