Lululemon pink sweater with crossover bottom twist back

Lululemon peachy pink sweater. Size tag has been removed but it seems medium-ish. The back is crossed over and twists at the bottom. There is a small dark spot in the back above and slightly to the right of the Lulu logo. I have laundered the sweater and it did not come out. It’s not noticeable when wearing, but I always point out any imperfections. See pics.
