I love the MSFs out of this collection. The first time I saw them in person, I passed on all three. I didn't even try them on.
Then, the second time I went by, weeks later, I tried them on and I loved all of them. I ended up with all three MSFs and the 165 and 226 (?) brush. I love the 165 but haven't done much with the crease brush yet.
I'm NC40.
Brunette is an awesome awesome color as a blush. It's the perfect rust red/brown. I really love this color and it's pretty unique to the MSFs. I can see why lighter girls would shy away from it though.
Redhead is my favorite out of the three. It's also a pretty unique colored MSF. I've been using it for blush and highlights. I really love it on low makeup days.
Blonde is really nice too. I swapped away Petticoat but I love Blonde. I also use this as a blush and highlighter.
The quality of these MSFs seems so much better than others. I've had alot of MSFs too -- including all the way back to Metal Rock, New Vegas, Gold Deposit 1st releases. The pigmentation is so fine and the 165 is the best brush for them too.
Love love love all three MSFs. If you didn't try them on and passed on them, try them on. You might change your mind.
Hope that helps!
