Vanity Fair Response:
The picture posted on the website is correct for this style.

Vanity Fair Response: Since this style is 100% nylon and doesn't have Spandex to stretch, it is cut larger.

Vanity Fair Response: The Vanity Fair Body Shine Illumination Brief Panty 13109 is available in size 6 on the website. Perhaps they were out of stock when you ordered. You are correct that the fit of 13109 is completely different from 15712 due to the spandex and coverage level.
