I just made arguably the best purchase ever - these J. Crew signature leggings ($39.50). I panicked that the leggings I was wearing were see-through so I went and bought these and they are amazing! Not only are they NOT see-through but they also are thick and help smooth out lines. I bought them one size too big so they actually look like slim black pants, but are as comfortable as wearing sweats to work. I feel like I seriously just pulled one over on everyone.
