I always use a base coat. The one from Poundland is super Make Up Gallery Ridge Filler Base Coat. Probably been using it for 4 years or more? I think it is as good as the high ends one I have tried before: a-England and Butter London namely. Hmmm rarely wear a top coat but if I do, it is always China Glaze Fast Forward - it kinda smells like sherbert too.
I've not tried either of those base coats, the Poundland one being good is great more money for polishes ;)
