Puff Sleeve Button-Up Top

I bought this in black in a sized medium. For reference I'm 5 ft 6 and 152 lbs. I feel that it runs true to size. I love this blouse for work, the buttons are hidden so it makes the front look polished. You can wear it with dress pants or for a business casual day I can see wearing this blouse with dark rinse jeans and a belt with kitten heels. It's an extremely versatile blouse. Also, there is a little poof in the shoulder area as that's how it's designed.
