So far I have ordered from:
Alima - I absolutely love their blushes. Their satin matte blush in Pink is my favorite, it's a great no-nonsense color which looks great with every look. I also love their brushes and some of their e/s (Chai and Nymph) are great as well. If you like natural colors this is the company for you, their CS is also one of the best !!
EDM - One of my favorite MMU companies. Their foundation is amazing and I found a great match in Cool - Fair Medium, they have a great variation in blushes (Nick Nack, Pink Ribbon and Soft Touch being my fave) and you can't beat their prices. The fact that you can order a free sample kit everytime is great as well
Fyrinnae - Their foundation in Pyrite and rice powder primer are HG staples for me and their e/s range is absolutely amazing. Their samples are VERY generous as well.
Lily Lolo - They have some great products in their range. Their foundation gives good coverage and I really like their Cupcake blush and Waikiki bronzer.
Lumiere - I got one of their sample kits but honestly wasn't impressed. Their foundation shades looked off (too yellow) and the blush I received in shade Poppy was lovely, but too chalky. Very fast international shipping though !!
Mad Minerals - Their foundation was okay, but I found their e/s a little too shimmery, but overal a good company with a wide variety of products.
Meow Cosmetics - The jury is still out on this one. Their foundation shade in Frisky Chausie was too light (shade is similar to EDM - Cool Fair) and their Teenie Weenie Bikini bronzer was so shimmery, I looked like a discoball. I also hate the fact that the samples come in baggies, which makes it very difficult and messy to apply. However, I did like their primer powder and Firefly blush in Shimmer (a peach, pink, nude shade).
Pure Luxe - I am absolutely in love with their Blushing Bride blush, Aprils Mix and Beach Babe bronzer and I will definitely order full sizes ones my samples are finished. They also have a great range in e/s (although too shimmery for me) and their ordering system is very simple and easy. Another fave !!
