They're probably his.

Go to your house, pull out a pair of boxers from under your bed and ask if they're his..

Or....she can just take the tank top and the bra and shove it up his ass!

Probably his. Haven't you ever heard of a manzier? ah Seinfeld.

What a weirdo! Dump that crazy cross dresser!!

So if OP had to go back to get some of her clothes, does that mean she has left naked?

Never mind. OP probably stayed the night and change back into those clothes and forgot them. I wish it was the other option. -_-

If she DID have boxers to pull out to begin with then she deserved it, so that's not really a valid response...

he might be interested in a 3 way

OP's Boyfriend: "Uh, they belong to my sister."

59- umm. considering that it was in his room, I think that would make the situation worse...

LOL, they're probably her best friends or someone close to her, haha

If they do belong to someone close to her... well then that's just fucked up.

48, I dunno, it could be a kinky situation.

How long has it been since the underside of the bed was cleaned? could have been his ex's!

Yeah, "haha"

Are u sure it's not urs?

yeah.. bc who really leaves after a hook up with no shirt and bra? especially when bras are like 60 bucks or more these days.

His mother's.

I noticed you still call him boyfriend.

He was drunk don't worry

yeah totally! cheating is okay when your drunk! note my sarcasm.

65, obviously you didn't note HIS sarcasm..

maybe he was doing his moms laundry...or his dads 0.o

i see what you did there.

Maybe he likes to dress as a girl in his spare time

Dont knock it till u try it dude

You should probably check under the bed to see what else he's hiding.. Maybe the girl that goes with the clothes is there too..

Hopefully alive as well if not then that would be a completely different fml for those involved

....a gift?

How creative and thoughtful of him!!! "Are these yours honey?" "... No!" "They are now!" "Awwww, thank you so much!! I've been wanting this top for months! I love you."
