Bikini so teeny

I recently bought this essie nail varnish and it's my first ever one! It's a pastel blue with a slight glittery/shimmer finish which is ever so subtle but looks very pretty! I've heard good things about essie  but didn't know what to expect, so far I think it's pretty good, 2 coats and its opaque and the brush is a nice thick size making it easy to glide across your nails. 

I find it so difficult to pick essie nail colours because there's so much choice! What's your favourite colour?
