I've been using Bare Escentuals for years (buying mainly off Ebay), but someone recently recommended Pure Luxe Cosmetics to me. They have very generously sized samples for very cheap and her range of eyeshadows are amazing. I placed my first order with her around the first of August and was so pleased that I just placed a second order a few days ago. I understand that once you find the foundation mix you want that if it's a combination of shades, that she will custom mix it for you. If you use one of her primer powders, then the foundation, then one of her finishing powders her makeup stays all day without looking chalky like the Bare Escentuals do. and I'm talking as someone who lives in steamy, humid East Texas. If her makeup will stand up to our heat and humidity it should stand up anywhere. It's applied a little differently though. You still swirl and tap, but you don't need to buff it in, just sweep it on with a very fluffy brush in very thin layers. It great and much cheaper than Bare Escentuals.
Another tip: If you go to makeupalley.com and just type in mineral makeup in the bottom box, a whole bunch of Mineral Makeup brands will come up and you can read reviews other consumers have written.
OT: has anyone tried the Eye Buki, Blending, Heavenly, or Soft Focus brushes from Bare Escentuals. I just recently won several an Ebay and am so impressed. They are so much softer than their regular application brushes. I admit I'm a brush 'ho and have tons of makeup brushes, but these are really, really nice.
