Hi! I haven't personally tried the Stila Darling lipstick, but after looking it up online I can suggest the Smashbox Lip Enhancing Gloss. I have this in the shade Afterglow, which is a pale peachy pink color with an amazing sweet, vanilla scent. (I know it says it is out of stock online, but check it is probably in a store.) If you want to try a different color in the line (hopefully they all smell the same), here is the link:

The only lipstick I can think of that has a vanilla scent is the Lorac Cream Lipsticks! I suggest the shade Color Long Kiss - shimmering light pink. It has a great color pay off and has a slight sheen to it.
