Lululemon cropped leggings

My sister gave these to me and they look and feel hrand new. There is no tag, but I own a good bit of Lululemon and believe they are a size 4 because I am a size 6 and they are a bit tight, which is why I need to sell them. They have a phone pocket on each side and a pocket hidden in the waist band. They are not aligns but the line that is suited for weight lifting. They have a good bit of compression but I know they would feel amazing if I was a bit smaller in the hips.
