At least Trisha (a) acknowledges her size and doesn't (b) tries to dress appropriately for itThere's no comparison! In fairness Trisha is starting to have a waist. She looks a million times better than that other animal.
We can all carry extra weight, or be thin, or be muscly or whatever shape and size. And I'll be the first to admit I live in gym gear / leggings when I'm not leaving the house but there's no excuse for wearing tacky unflattering clothing three sizes too small just so you don't have to admit that you put on weight.
Sarah will keep going and then seep into a depression after the baby is born when she realises she has no more excuse for being bigger than her twice bought house.
