Some of us are too old to be stricken with Bieber fever, but I really don't think any of us are ever too old for gold — polish, that is. Justin's Nicole by OPI One Less Lonely Girl nail polish collection sold out at Walmart almost immediately last month, but a whole new crop (including eight more colors) has been released at a wider selection of stores, including Ulta, Target, and Walgreens.

Putting the whole teen dream thing aside, I have to say that I was pretty impressed with Not a Gold Bigger ($8) from Justin's second batch of polishes. Almost an old-gold shade, this muted metallic is neither too shiny nor dull. Because it's also not very flashy, it's surprisingly very wearable for daytime. Read: you won't feel like a teenybopper if you're donning this particular auriferous shade. I like to think of it as almost like jewelry. Two thin coats were plenty, although the next time I wear it, I'll definitely be using a topcoat to prevent chipping.
