OK ladies....
Major disclaimers: It's already dark, I didn't do a real mani, and my hands are a mess. And I'm recovering from surgery. So please excuse the messy hands.
Here's a quick swatch comparison between Guerlain Baby Rose, Dior Tra La La, and Tom Ford Pink Crush, all 3 coats:
Looking at my hands, Pink Crush is the darkest and most blue based pink. Tra-La-La and Baby Rose pull more peachy pink on my Burberry Trench 02/202/Chanel 12 skin. I'm almost pink naturally.
Tra-La-La and Baby Rose are similar, but I prefer Guerlain's formula. It's also slightly more opaque in 3 coats.
