Frankel's definitely proud of her fit figure -- back in July she posted a picture wearing her 4-year-old daughter's pajamas.


"This is my daughter's nightgown and PJ shorts. Think we're ready to start sharing clothes yet?​," she captioned the photo.

The 43-year-old received a ton of flak for the candid snap, but the New Yorker fired back at her critics.

"BREAKING NEWS! World Scandal: Former reality star, failed talk show host & cocktail maven jokes by wearing her kids' pjs! #itcantbetrue," she tweeted at the time.
