Lululemon Athletica Swiftly Hip Length Size 6 Chilled Grape

I bought this directly from lululemon about 6 months ago. I removed the tags and wore it ONE time for about an hour and decided its too small for me. I always remove the size tags from my lululemon, but I have my order confirmation and the imprint on the hem that confirms it's a size 6. this is in new condition, there are no snags or flaws. it looks and feels brand new. from a fragrance free household. color is chilled grape.
