Brandy Melville Thermal Long sleeve top

Unsure of the exact name of this top but I bought it this winter season. Never worn and it is in perfect condition. Cute 3 button detail, can be worn buttoned all the way up or down. Very versatile. - inseam (shoulder to bottom): 20” - pit to pit: 16.5” - waist: 15” - length of arm: 28”
