How did I miss this thread??
I'm a lipgloss-and-go girl. Heaven knows my commuter-rail trip is long enough to put on a full face of makeup, but 99% of the time I just shove a lipgloss in my pocket and book it for the train. Eyeshadow lurks in my work bag in case I decide to go out after work.
I got a sampler of 5 MAC lipglass shades a few months ago, in various shades of pink, and I usually carry one of those. When I wear red, I use a Prescriptives lip gloss, which I call "lip-repellent" - I have to reapply it so often that it's seriously annoying. I won't be buying Prescriptives again. The MAC stays on, though I usually have to reapply after lunch, but that's better than reapplying every five minutes.
