I really love Essie nail polishes - there's a great range of colours, the bottles are super cute and, despite what I've heard from others, the formula of the colours I've had have all been great.
My favourite Essie polishes are Go Ginza, which is a "cherry blossom" purple toned pale pink, and it makes your nails look so pretty and clean and just very lady like. This made my nails look good even when they were little stubs! My other favourite (which is the favourite of many people) is Bikini So Teeny, which is a really pretty light sky blue. This looks amazing with a matte top coat, on your toes, with a gold or silver accent nail - anything goes! Plus I find it makes me look more tan than I am :) If there's one Essie I would recommend that everybody stay far far away from, it's Shake Your $$ Maker. Sure, it's got an awesome name and you think green nail polish will be awesome, but the formula is the worst out of any nail polish I've ever used. It's streaky, and you need about 5 coats to get it opaque, and even then it's still patchy. Nope. Steer clear of that one.
love their color range and that you can get these on sale at some online stores (however color choices are limited then). I only have two shades, watermelon and midnight cami (which is a darker shade of navy blue) and i love both!
