Hey Chrissy, we think you missed a button -- or rather ALL of them!

Chrissy Teigen let her boobs doing the talking when she wore a plunging blouse by Anthony Vaccarello (which basically just looks like a shirt that never got buttoned), allowing anyone more than a peek at her lace bra. In addition to the exposed top, the super sexy lady wore a pair of sheer pants for a romantic dinner with her hubby at Craig's in West Hollywood last night. This gal certainly ain't no wall flower!

We have a feeling we know what John Legend's favorite game to play is -- peek-a-boob!

Despite never being shy about showing off her bod', Teigen recently said she gained 11 pounds while she was working on her cook book.

“I’m having a tough time getting back to my pre-cookbook weight. It’s only 5 pounds, but it’s frustrating. My tummy has always been my problem. I’ve never seen an ab, no matter how many crunches I do.” the 29-year-old said.

Well if you can't flaunt your taut tum -- we guess show them tatas off!
