And I thought about this subject. Now listen up, this has no empirical evidence nor do I want to sound like a Cosmo Magazine article save for a few smiles and laughs. Yet some of it may have a little grain of truth and accuracy, I really don't know. It's worth a read though, trust me on that.
Well have you ever been to a Pyjama Party? Did you really come into the party with your actual sleepwear? Honestly? Well if you did, let's take a look at what this may tell about you.
Flannel Pyjamas (Pajamas)

Silky/Lacy Lingerie

Teddy/Cotton Camisole/Tank Top and Shorts
You have to be very confident, playful and comfortable in your own skin to pull this off. If you will be romping around with this on, you completely trust and love how your body looks. (I just love how that sounds because as this is my staple look, it is mainly because I always thought I will grow up to be a boy. And I just honestly never outgrew the "look.") You tend to be the more adventurous type in lifestyle and sexual preferences. You don't really give a rodent's ass if you will have sex in the kitchen with the lights on. You are spontaneous and generally sexually charged. (Hmmm...)
Naked and Raw (Or just nek-ked)
They say, chances are, you are a spirited idealist, a natural leader. Quite innovative, a bit reckless and adapts easily to change. If you sleep in the raw with your partner, it creates the strongest level of intimacy between two people. Even if you are not having sex, there is an absolute erotic and sensual edge into it. Plus the bonus factor that the absence of waistbands and elastic straps will never make you look fatter. (Hey that makes a lot of sense!)
