Nars ( especially orgasm) lipgloss is amazing. Nice texture, color, and staying power.
Stila Lip Glaze- cute packaging, nice texture, and looovely sheer/tinted colors. it can be steep for some ( $27.50..I think) but it's well worth it to me. I'm hooked on apricot.
DuWop Lip Venom ( or reg. or flash). This is, in my opinion, the best little lip plumer. It comes in a darling little glass vial-type thing, and it stings when applied. Nice, short-term, bee-stung lips effect.
Hard Candy has some fun ones ( especially this sparkly pink color I have)
Some notable runners up are certain clinique glosses, and very surprisingly, the little American Girl lip glosses we sell at BBW. They go on sheer w/ light shimmer and they have yummy flavors. For only $4.50 you can get lots and keep them in the purse, car, wherever--- who cares what happens to them. lol.
