I love this manicure! I usually do not pair orange and pink together, but these pastel colours really seem to go together well. The polishes I used are Nubar "Orange Creme" and Quo by Orly "Cotton Candy". For the thumb I used a piece of tape to make a nice straight line. :) These colours remind me of orange and pink creamsicles, and although pastels are typically more suitable for spring, I think these colours are great for the summer! I am currently also wearing Cotton Candy on my toes and it looks great against my tanned skin.
The only annoying thing about these nail polishes is that both of them took 3+ coats to achieve full opacity. I guess that's what you get with pastel colours. Next time I'm going to try using a white coat underneath to see if it helps - I've heard that it works great with pastel coloured nail polishes.
