Here's a review on Sinful Colors in Let's Talk. This is a very deep purple that has purple and red micro shimmers in it. It looks great in the bottle and on the nails. The first coat is a little bit transparent and a tad streaky, but as it dries it generally evens out. After the second coat you have a nice even color that is completely opaque. It has a great consistency. The red shimmers that are in it really give it the extra something that I am always looking for in nail colors. I really enjoy wearing this color especially when it is sunny and the red catches the light. Wonderful color as with most of the Sinful Colors that I have.
If you are looking for a deep purple that is affordable but long lasting this is your color right here. Here are some pictures (slightly crappy but the best I can do with my picture phone).
