Victoria Sport cutout keyhole back tank top

Victoria Sport cutout tank, size Large. It's a blue, almost teal color. Very, very cute top. Has seriously BARELY been wore. I bought this new optimistically, but it turns out my arms and back aren't quite toned enough for me to comfortably pull this off. It deserves to be worn, it's so cute. Pit to pit measures 17 inches, and from the top of the shoulder down to the front bottom hem is 26 1/4 inches.
