Pregnant Kim Kardashian has been wearing upsized, form-fitting non-maternity wear throughout most of her pregnancy, but on April 3, we got a double fashion surprise. Not only was the star wearing a flowing maxi maternity dress for her froyo outing with step-brother Brandon Jenner and his wife, Leah — the frock was a hand-me-down!

Kourtney Kardashian wore this exact dress back in June, when she was very pregnant with little Penelope Disick. Despite the fact that Kim and Kourt share DNA as well as clothing, we can’t help but notice that the dress fits each sister very differently. That’s not surprising, however, given Kourtney’s slightly more petite frame.

Kim — whose bust appears to have grown two full cup sizes larger since becoming pregnant — is practically spilling out of the top of the dress. On Kourtney, the bustline of the dress is fairly demure by comparison.

If you ask us, Kim probably could have benefitted from a better fitting bra to wear under this dress. That said, we still enjoy seeing Kim embrace her older sister’s earth-mother-goddess style. (Just don’t give up on deodorant the way Kourtney did, Kim!)

Having seen each sister in the same dress, we want you to weigh in. Whose baby bump (and lovely lady lumps) suit it better: Kim’s or Kourtney’s?
