The first essentially says, "I think I have big hips, so I am using this frilly sht to try to cover that" but it draws attention to her hips, which I think are fine, but I doubt she would take that dress off, that night. She looks like she has a stick up her A$$!!
The second says "I think I'm going to get a hot guy, with the slit, almost showing, something, but it should be sleeveless, lower-cut, more accentuating her breasts, with her look, and that would get the 'invite' to a 'night-cap'!
Tight, long skirts just aren't hot, but free-flowing long skirts, with slits up to the high thigh, , with dancing, and touching, are more 'inviting'!!
