Vintage Old Navy V neck sweater with toggle buttons, Sz S

This is a vintage Old Navy pull on sweater that was very vell loved. It has 2 brown toggle buttons in the front and a collar around the v neck. It is see-through throughout most of the sweater, so it should be worn with something underneath. It is Navy blue. There is minor pilling on the insides of arms and along sides ( I tried to picture) but is in overall good condition, no holes, and has lots of life left!
