Do or Don't?

I've heard about a lot of random advances in beauty/fashion lately, and most of them straddle the line between insanity and genius IMO. I just can't decide.

• Eyelash extensions. Apparently they cost the same amount overall as getting manicures each week (not that I do that), and are great at attracting the dudes. But what happens when your man sees you without your "come hither" eyelashes for the first time?
• Pajama jeans. I heart pajamas, so this sounds fabulous in theory. But...uh...really now? Maybe they'll make cuter ones in the future.
• Bootights. Now, these sound like something I might actually buy. Plus, Oprah endorses them!
