I'm not entirely sure why this was in a "Summer Nails" box as I wouldn't particularly call it a summer shade but never mind! I've been really loving nude shades recently as they go with everything and always look pretty classy and sophisticated. Butter London describe Yummy Mummy as a medium beige colour to suit all skin tones. It's actually slightly more purpley-toned than it looks in the photo... my camera was being stubborn and didn't seem to want to capture the colour quite right! It has an ever so slight shimmer to it in the sun and under bright lights too.
The formula of this nail polish is close to perfect! It applies really well thanks to the decent brush, doesn't look streaky and is dry to the touch within 5 minutes. Only thing is it did take 3-4 coats to get it totally opaque, but it definitely doesn't look or feel like there are so many layers on my nails! If you did want a more subtle look though you could easily get away with just one sheer coat.
What do you think of nude nail polish shades? Have you tried Butter London before?
