I have been non-stop wearing this By Terry Nail Laque in 'Fire Game'. At £21 they're not the cheapest around but I can justify this, promise.
There's no need for a base coat as they have a conditioning and strengthening formula making them like a treatment for the nails, they don't stain, they have an opaque finish in two coats, are long lasting, rapid drying plus the whole range is full of gorgeous plums and burgundies too.
I picked mine up from Space NK and will definitely be trying out some other shades. Have you tried any of the By Terry polishes?
