Floerns Women's Double Button Long Sleeve Round Neck Asymmetrical Blouse Tops

What color are the buttons on the black long sleeve shirt? Do you have one with gold buttons?

In the sleeved version of this asymmetrical jacket, how much room is there in width for the upper sleeve, XL? Sellers only, unless you have purchased.

The description says sleeveless, however there are a couple in the pictures that do have sleeves. If I pick one with sleeves, is that accurate?

Are buttons metal or plastic?
