Ardene Sweater w/ Black & White Pattern

Awesome sweater by Ardene (note: NOT Arden)! The black and white pattern resembles houndstooth, but it's actually little triangles once you look closely! Round neckline. Please note: there is one random spot on the back of the right sleeve - one black triangle from the pattern is slightly bigger than the rest. For the 2nd last photo I took a close-up of how small it is with a measuring tape. In excellent condition, and it's size S.
