Lululemon Wunder Puff Pink Puffer Jacket super crop dahlia mauve coat Sz 6 DHMU

Lululemon Wunder Puff Pink Puffer Jacket super crop dahlia mauve coat size 6 Has “water stains” /discoloration. I used laundry detergent made for down fill feathers and it’s still stained. I don’t know exactly what the stains are or how to remove them. It’s not really noticeable because they blend with the ripples in fabric so if you need more photos just let me know. No holes. No hood
