NN Sexy but cracks in dresses drives us wild!

[thanks_a_lot]

You know, those sexy loose dresses that seem to sneak way up into their but cracks. They show the sexy shape of the cheeks! They are usually flat (not denim/heavy fabric) thin fabric longish dresses. They can't be tight, if they were, they would not ride up into the butt crack.

Everyone has tight skirts, upskirts, nudies, etc. I'm looking for NON nude dress but crack pictures. They make my imagination run WILD!

See attached for a hard to find picture of what I'm looking for and what I'm NOT looking for. Tight dresses do not show the crack between the two cheeks, they show nothing, very boring to me. There are posts for tight dresses, this is NOT it.

Please, dresses/skirts only, there are lots of other posts for shorts/spandex/tights/etc.

poll too please.
