I hear you about trying to finish the ones I already own, BUT......
if there was ONE product I can really justify overpurchasing because of how much I use it...it's definitely lipgloss! CAN NOT LIVE WITHOUT IT!!!!! It is the only makeup item I leave the house with (no matter how much work goes into the look in in the morning) and I am sick of using my HG lipglasses of Lovechild and Soft & Slow. Time to add a few more to the repertoire! I am loving my new Narcissus but I am also very stoked for Famously Fab, Comfort & Joy, Tour de Fabs, Rich & Witty (which I am actually hoping is a dupe for Soft & Slow since I only have one more back up of that one in my stash!). It has been far too long since MAC has come out with lipglasses that I have been interested in, and I am ready to SPLURGE!
To me it is way more justifiable than gobbling up more e/s quads from Shop/Cook, because I can make eyeshadow colors myself with all my pigments, but making lipglosses is much harder!
(But I am somehow sure I will also end up with those quads....)
well i love my lip gloss however i really should use up all the ones i already have... i feel bad because i ignore them so much
