Ben Nye Banana Powder
I swear to baby Jesus, I grabbed this and put it in my bag. I don't know how, but it must have snuck out! I use this to set my highlight, but I planned to use it on my whole face because I had to be pale for my costume. Since I forgot it, I had to substitute my regular Mac Studio Fix powder. Not my first choice, since it was darker than the look I was going for, but I'd rather be tan than shiny.
Sleek Blush By 3 in Sugar
This was also going to be for my costume. I needed a red/orange blush. I accidentally grabbed my Nars duo in Sin/Casino instead...which is similar on size & shape. To cope, I mixed my bronzer with Daydreaming eye shadow by Mac. It actually worked out pretty well!
Luckily, that's all I forgot. And I was lucky to have decent substitutes in my stash. So next time you're on vacation and you find yourself missing a key beauty product, take it as an opportunity to shop your stash...don't panic!
