This beautiful blouse is by cool Danish brand, NuDenmark, and is a perfect top to wear with skinny jeans or leggings due to the longer length. It has a button collar, which can be done up or left undone (see photos). The length at the front can be tucked in a bit at the front, or left loose (again see photos). The sleeves have button closing at the cuffs. I have worn a black cami underneath for the photos here, but it also looks good with a black bra.
