This is the other product I picked up at the YSL counter recently. I'd never heard anything about their nail polishes before and since I already have a few nail polish brands which I'm pretty loyal to, I was reluctant to try it. However, after swatching it, I changed my mind.
The formula looks really thin and watery which was off-putting as I'm not a fan of sheer polishes but it's not sheer when applied. Because it's of the thin formula and wider brush it glides on to the nails so easily. I applied two coats and it's completely opaque. I can't say anything about the wear time just yet but that's not usually an issue for me since I change my polish so often.
(apologies for the slightly messy nails...I got a bit over excited about this post!)
The packaging is gorgeous and the shade Rouge Dada is a great classic red. These are not cheap at £18 each (link) so I'm glad I went for a really wearable shade.
Have you tried any of these?
Ps - I should add that the staff at the YSL counter in Debenhams on Glasgow's Argyle Street are lovely!
