I only think these belly cakes are appropriate if the mom's figure actually resembles anything similar to the cake. If a women is overweight and already feels like crap because of it, why rub it in with a beautifully figured woman on a cake? Besides, this cake is tacky, look at the outfit. That is totally not appropriate for a mom to be wearing.
All if have to say is that this baby shower cake has no class. Who wants to be reminded of surgery to get your baby out of your womb? It's just so distasteful. I really hope it was made for humor sake only and not really used at a baby shower.
