My personal preference is MAC, especially their eyeshadow and blush.
However, since our budget has changed I've had to find alternatives to some of my usual purchases. I do still buy MAC eyeshadow and blush. Not as much, but their excellent pigments and ability to last awhile justify the cost.
I also have to be careful with my choice of powder and foundation, thanks to terrible skin. BUT I've recently found an incredible drugstore brand that just might replace my expensive stuff!
Here's what's currently in my makeup bag. I do have an additional bag with my MAC eyeshadow, but I was gifted the below Smashbox set and it's been great for my everyday wear.
Foundation: L'Oreal BB in Medium (I got it at Target and it's been awesome)
Powder: GloMinerals in honey light (I get it at Beauty Brands, but thanks to my BB cream I don't need this everyday anymore)
Concealer: L'Oreal true match in warm
Bronzer: Bare Minerals compact in high dive
Blush: MAC in pink swoon
Eyeshadow: Smashbox softbox in photo op palette
Liquid eyeliner: Mary Kay in black (I use this on my top lids)
Pencil eyeliner: Revlon colorstay in navy (on the bottom)
Mascara: Mally in black (this was a gift and has been great! Normally I use L'Oreal)
Brushes: Most my brushes are Sonia Kashuk from Target. One is Bare Minerals, and two of the eyeshadow brushes are Mary Kay.
