This No7 Stay Perfect Nail Colour in Betty Blues has to be one of my favourite No7 colours. I only have a small bottle from a gift set but I really should get a full size bottle.
Before I tried it I thought it would be too dark but due to the reflective elements, it has a lovely depth to it and looks quite special. You can just about see them in the photo – it’s very difficult to photograph so you just have to try it! I think it’s a great colour if you want to go dark and sophisticated for winter, but don’t want the usual red or burgundy shades.
Two coats are needed to get a good intense colour. It’s not quick dry so you’ll need a quick dry topcoat or spray. As for the formula or application, it’s ok – not special and not bad. I actually don’t pay attention to the practicalities, as I love the colour so much!
