So I'm not a huge lover of matte top coats - often finding they just make you look like you've scratched the sheen of a nice glossy polish. But I think it all depends what colour you're top coating and also the quality of the top coat. I've found one I really love from Models Own Pro which gives a lovely satin finish rather than dull matte.
I think the colour combo works really well. The key is to use a muted sophisticated colour for the base and then a colour that really pops for the tip. It's a great way to venture into nail art or to take a boring work mani to the next level without being over the top!
Happy painting... the nailist xxx
