Lululemon pants

Lululemon pants. Mystery item, I have no idea what style these are! Also not sure of size, the tag from the consignment store I got them from said 6. I am usually a 4 in Lululemon and these are too big on my waist so may be a 6? Still has consignment tags on them, I never wore them after purchasing White. Thin somewhat sheer fabric. Wearing nude undergarments and looks fine. Back and front pockets. Stretchy wide waistband
