With the sheer fabric gaining popularity, the see-through dresses is a common trend among the celebrities. Celebs are often seen in such dresses, which even give their fans an eyeful of their private parts as the fabric is way too thin and usually they forget to wear anything beneath. Below are some(NSFW)pictures of the best see-through dresses of 2009. Scroll and have a look.

Rihanna

I guess after those nude picture leak, Rihanna doesn't worry about which body part of her's is visible to the crowd! As that could be the only reason, she was seen without a bra and a panty in a sheer fabric dress at the Paris Fashion Week.
Lady Gaga

She had to be in this list! We can see her surgically enhanced breasts in this outfit very clearly. And I wonder what would have happened to her male body part in this see-through dress!
Alexandra Kerry

Ok, this can't be accidental. Either Alexandra forgot to wear her bra or she wanted to gain attention at the red carpet. Well, I don't know about the former, but the later surely happened.

Well, Madonna's legs are quite sexy and we got to see the full view when she arrived at Vanity Fair Oscar After Party.

We have always seen that this female has the guts! Blake Lively was seen at the Sherlock Homes premier in a lace clad dress. Well, we could peak into the lower body of the actress a little bit!

This see-through outfit is quite sexy. Hayden carried her laced attire very well. It is giving just a little show, that’s it!

I don't know to call her what? She was looking gorgeous even in her intentionally or non-intentionally flashing breasts. You decide that.

Well, Pammie, I guess the cut was a little more higher than usual. She was seen flashing her panty's at the 6th Annual Hollywood Style Awards.
