This Full Fashioned stocking features a black seam which contrasts with the ultra sheer Beige leg.  These are authentic full fashioned stockings, complete with the finishing hole in the top welt, but offered at a budget price. The authentic vintage style 15 denier are 100% flat knitted nylons, just like they made in the 50's. The Contrasting black backseam makes these stockings especially attractive, and is only found in far more expensive stockings.  Please read the following for sizing:  These stockings are very sheer and are not stretch stockings.  They only stretch as far as the actual knit of the nylon allows them.  The S/M size should not be worn by anyone over the weight of 90-120lbs, and no taller than 5'2.  The M/L size should not be worn by anyone over the weight of 120-150 lbs, and no taller than 5'8.  The top welt of the M/L size only measures 20" so if your thighs are larger around than that you should stay away from these stockings.  These stockings are not for heavy or fat legs.
