For a relaxed casual outfit, pair a red check long sleeve shirt with a white crew-neck t-shirt — these items work really well together.

Many people mistakenly assume that just because you need to get bundled up you have to sacrifice on style, but it's just not true, and this ensemble is a vivid example.
