I just got back from shopping with my daughter and I was going to start a thread for you and then I saw this @Noel7. lol!!! What a coincidence.
She went to Walmart and while i was there I found some really cute polishes and they are made by a brand called Salon Perfect. It is similar to Sinful Colors in the fact that it is a really decent nail polish at a good price. I think they are slightly more expensive than SC but not by much. It think each bottle was around $3.25.
Anyway, they had a collection called Neon Pop. Some really cute bright colors and I am assuming it is their spring or summer collection. Like other neon collections, it comes with "white underwear" meant to be worn under these colors and to make them brighter and to pop even more, it is just a white nail polish. They happened to be out of that but I do have white from another brand I can use. I also wanted to see how these looked without the underwear. I bought about 7 bottles and I really love these even without using underwear. They are bright but not super bright and would be perfect for doing a skittle (A manicure where there is a different color on each nail) Neons also dry really quick (which is nice) and they do dry down rather dull so you will need a top coat to bring them back to life.
I looked for swatches so you could see what these looked like and I have to say that Neons are notoriously difficult to takes pictures of and these are no different. As a matter of fact mine look very different from these swatches and I think they look much better. The Bermuda Baby is the blue and it is just gorgeous. It looks so different from this swatch. It has a slight shimmer that you really can't see here. A lot of them have this slight shimmer. This is one of the prettiest blue colors I own. I also wanted to say that many times the bloggers hate Neons but only because their formulas are so difficult and you need many coats. I am seeing that most bloogers loved this formula and I thought it was great. I will give it a try with the white underwear but right now I am loving them on their own.
I don't normally ever shop at WalMart so I am really glad I did today.
