I realized that I wear button-up shirts a lot, both mens and womens. I really like button-ups and I think they are a perfect way to add class to an outfit while at the same time can be casual. They look good with or without heels and usually can be worn in a variety of ways: underneath a sweater or shirt (here and here), with a vest (here), or just by itself. I think it's a good staple piece to have because it can be worn in all seasons and is a really good layer. It doesn't matter if it's denim, cotton, or silk. Button-ups can be dressed up or dressed down and even worn in different ways: tied at the front, with rolled up sleeves, button all the way, open, around the waist, etc. Below is a great visual of the versatility and necessity of the button-up.
