I've got more lipglosses and lippies than I know what to do with. TBH, unlike things like foundation, I think you can get away with cheaper brands and they're just as good. For example, A rimmel or revlon lipgloss will be just as good as a Chanel one...the packaging just won't be as pretty
If you're looking for a pinky brown natural colour, check out Bobbi Brown. She's the queen of natural shades. I've got a lovely lipstick called "Rose". I honestly wouldn't bother forking out too much for a gloss unless you're a sucker for the packaging (which I am).
