My favorite designer is Ralph Lauren because I feel like it adds a sense of class to everyday wear. He makes a variety of polo's and button downs that you can mix and match to make one outfit become two or three.
His clothes are very comfortable and you still look a little more than casual when you wear them. I feel like I always look my best when wearing his clothes. His styles are always classic and up to date with little tweaks to the main items to make them newer and improved.
