Since these are all very flattering colors, I imagine you could pull off any of them. Yummy Plum would be lovely for spring, and Half Naked would be a great everyday neutral staple. I would only get Clear or Candy Gloss if you are not looking for much color, but you like to layer over other glosses.
I have the Sexy Mother Plumper and while I admit it tingles at first, I cant say I see a dramatic plumpling of my lips. I have normal lips and it doesnt do much for them to plump. Fun to use, but I just go with with fav lip glosses now, since I cant stand a sticky lipgloss, and its a little sticky.
