Hmmm. Either we've suddenly developed X-ray vision, or see-through garments are getting some serious play of late.

Just a day after Jessica Biel flashed her black undies through her sheer red gown, actress Blake Lively stepped out in a short navy dress with a transparent midriff and floral overlay from the Chanel 2010/11 Cruise collection at New York City's Cinema Society screening of "Twelve".

The "Gossip Girl" star paired her revealing Chanel frock with Christian Louboutin cork pumps, Ofira black gold-and-diamond earrings, and a Lorraine Schwartz "To Be Happy" bracelet.

It's not the first time Lively's worked the sheer trend -- remember that lace dress? -- but the starlet does seem to have acquired a new fondness for showing skin. Exhibit A: The plunging top she wore to Comic-Con.

Hey, if you've got the flat abs (or boobs) to get away with it, don't let us stop you.

Let us know what you think of her look and rate other celebrity ensembles in the below gallery.
