skeevage

skeevage combines two common words: clevage and skeevey.
skeevage is cleavage that's on a skeevey woman.
it may have wrinkles, blemishes, pertruding bones, or freckles among other things.

impulsively, my eyes were drawn to her low-cut dress when i realized i was looking at common skeevage.

Skleavage 

Skleavage is a portmanteau or blend of two words Skiing and Cleavage.

It is the cleavage shown off on a sunny day while skiing by woman that find themselves dressed too warmly for the unexpected warm conditions.

There was some great skleavage visable from the ski lifts out on the slopes today.
