For an ensemble that's effortlessly sleek and gasp-worthy, pair a white crew-neck t-shirt with black dress pants. And if you want to immediately dress down your look with a pair of shoes, add a pair of white athletic shoes to this ensemble. A practical example of functional fashion, this look must be in your collection when the cold days hit. If you frequently wonder how to dress appropriately for your age but also look fashionable, this pairing is a perfect example.
