If your looking for a really true silver, gold, or white e/s I would definitely pick up the Rocket City e/s trio in Beam Me Up. This trio is my favorite e/s purchase ever. I also have the Mac Daddy Martian trio and although these are good quality too the Beam Me Up trio has better quality. I don't know about the other trios as I haven't tried them yet. I also have Rocket city take me to your leader compacts, and all of them have are excellent quality, last forever, come in the cutest compacts intact with a baby lip brush and mirror, and have the best vanilla cakeish smell and taste. I would also recommend Rocket City's galactic gloss. They have the same great quality, great taste and smell, etc as the take me to your leader lipglosses but are in a tube instead of a compact.
I would definitely recommend almost any of Urban Decay's eyeshadows, as they are all great quality.
I would also recommend Too Faced clickable lipgloss pens. These I swear are my holy grail lipgloss. They last forever, have the perfect consistency, come in quite a few colors, each one of them has a different smell and taste according to its color but they all are delicious, and they are so totable. My favorites are first kiss and screen kiss. If you only buy one thing from Sephora ever it should be one of these
