Right- MAC's Studded Kiss
As you can see, both shades are very similar- but there is the slight difference in tone as mentioned above. Both lipsticks have an opaque, matte finish and look no different on the lips!
Vamp can be a little bit patchy, but it's nothing that is very noticeable and it's fixable with a bit of blending! All in all though, both lipsticks tend to be quite consistent in colour.
I've found that Vamp was quite hard to apply at first because it was so incredibly dry to the point where it felt like I had to tug to get it on, but as I've used the lipstick more... I've found that it's become a lot easier to apply- strange, I know! Studded Kiss is also a tad drying, but it wasn't as severe!
All in all, I think for the price difference, I'd give Vamp a whirl before Studded Kiss- after all, you're not losing a lot for £4.99!
