These are sooooooooooo sexy oh my goodness!!! I love these so much. It’s very seldom that I buy pants online and actually like how they fit!!! No need to size up or down..just take your regular size. It is stretchy but not too stretchy. It has a medium stretch so your regular size will do.. it is definitely true to product images. the fabric material is smooth and has a medium stretch. the quality is absolutely exceptional. it is a regular fit. it does not have a smell at all
