Lululemon Athletica 25" length size 6 leggings NEVER WORN - TOO TIGHT for me

Lululemon Athletica High Rise Leggings with hip pockets and interior back pocket. I am really a size 10, not a size 6. I THOUGHT that this would stretch but not to fit this size 10 thigh n' hip. These really are for a size 6 maybe a size 8. All of the seams are PERFECT - I put a foot in and realized these aren't for me. The seams are all perfect, the pockets are as well. I am terrible at returning things I don't wear thus why I have these leggings. Fabric is a great weight.
