Combining a blue plaid long sleeve shirt with navy jeans is an awesome pick for a relaxed casual yet on-trend look. Brown leather casual boots are a fail-safe way to breathe a hint of elegance into your outfit. You might think that just because it is snowing outside you have to sacrifice good style, but it's just not true, and this look is a striking example. This combo proves that dressing stylishly in your mid-20s is easier than one might think.
