I just got these stockings but the seller sent me a way smaller size (A-B) than I ordered, I e-mailed them telling them about the problem and will keep you dear buyer posted. I cannot tell you about anything about the quality or color because I have not opened the ones I received.

Ex Output:
Negative


Ex Input:
While the basic instruction is passable, the technique of most of the dancers, including the instructor, is mediocre to poor. What's truly terrifying is how frail and anorexic most of these women look. There's an unfortunate sort of L.A. starved-skinny bleached-blonde airheadedness to this production. Belly dance can be a powerful, grounded and grounding ethnic dance form; however this tape presents more of a "wrap yourself in sequins and wriggle for your husband" sort of vibe. Culturally divorced and ugly-American scary. Made me want to shave my head and get tattoos.

Ex Output:

Negative
