70’s style dark rainbow turtleneck sweater

Shoulder to hem length is about 21.5”. Bust is about 18.5”. Sleeve length is about 22.5”. Turtle neck length is about 6 3/4”. Has a small hole under the left armpit less than 2cm in size, another beside it less than 1cm in size, and another hole about 1cm in size at the hem of the sweater. The size on the tag says large but I wear a medium and it’s a bit tight on the sleeves and shoulder area although that may be due to my bust size (I wear a 32DD) so be wary.
