It's kinda like those bogus advertisements with before and after photos where the before picture has someone frowning in shade and the after picture has 'em smiling in good light. If anything, I prefer the skinny jeans. But perhaps I'm comparing an apple and an orange; even though they both have bottom heavy figures, i'll compare skinny and bootcut jeans on one person.
Okay, I can see that hips and thighs are more pronounced in the skinny jeans, but the others make her look bigger all over. How is that slenderizing? It strikes me as more modest and easier to kick off at the end of the day, but not more flattering.
