The problem could be Birthday Suit is a bad color for me. This is more like a gloss than a lipstick; the color has lots of shimmer and is quite pale even for my fair skin. The case is flimsy and does not twist up smoothly. I had a coupon and only paid $2 so I will use it as a base for some of my too-dark lipsticks. Does have SPF 15. I probably would have liked a more vibrant color better.

Im going to start off by saying that i do not like this lipstick, but i dont hate it. i feel that on its own, it sucks. WAY to frosty, it looks horrible on my tan skin. when i wear this, i always apply a few coats of a pink or red lip gloss over it to hide the color. i love wet n wild, especially their eye shadows and most of their lipsticks. but really, however, this just really disappointed me. Maybe it will look better on pale skin.
I also use this product as a lip highlight: i place it ONLY on the middle of my lips. it works better that way than the way i described above.

This is a perfect shimmery nude color with a hint of pink in it. Its perfect for the summer! Very pigmented, very shimmery, and has SPF!
Tip: ELF's Super Glossy Lip Shine gloss in "Candle light" looks great over it ;)
