Marrying a light blue denim shirt with a tank is a nice option for a casual yet on-trend look. Dark green athletic shoes will give a hint of stylish nonchalance to an otherwise all-too-safe getup. Seeing as it's blazing hot outside, this ensemble is ideal and entirely summer-ready. Just because you're in your 50s, doesn't mean you can't dress casually anymore, and this ensemble demonstrates just that.
