I am a fan of nail polish brands that do not put any formaldehyde, toulene, or DBP in their polishes, Zoya is a Vegan friendly brand and they have one of the widest ranges of colours.
I am pretty excited about the new A/W ’14 collection and will be putting my orders in soon, Entice : the non shimmery array of creme shades which includes : Nyssa, Claire, Margo, Genevieve, Ryan and Veronica
Ignite is a collection of deep colours lit by a gold shimmer, I have a feeling they will all sell like hot cakes! These are Autumn, Sansa, Remy, Teigen, India, and Yuna.
http://www.zoyanailpolish.com has the full range of its available colours and finishes and you can order from this site or type Zoya Nail Polish into the Amazon search engine and some are bound to come up!
