Teddy girl is like OPI's mod about you "sophisticated cousin". It's the same bold light milky pink but whereas Mod About You is a bit streaky and requires patience (regardless of how many coats), Teddy Girl applies much nicer. Teddy girl's requires two coats because the first coat will be a bit streaky (very common with these type of white pink colors) but the second coat makes it go completely opaque.
It's definitely a cool pink. It's striking on so much so that the entire week I had it on, not one day went by without getting a compliment on my polish. I'm not sure if the picture above makes it justice because the lighting was off when I took this but I highly recommend this color. It's perfect for all the pink lovers like myself.
Hope you all have had an amazing week.
