I thought about that about the fake Pregnant Bellies, IMO local Theater Drama groups would have some for their local productions. I don't live in the USA but I sure they hire costumes even sell props(which have sat there for some time it would be easier than buying from a store which could be traced. Couple years ago a few friends brought some Bellies Props from a local Theater group,they saw them when they were hiring costumes saw the props, offered money to buy them on the spot,the person excepted their offer. They were doing Musical 'Princess Ida' they thought it was joke with the cast and Director for Dress rehearsal . MF could hired costume with fake belly and never returned it. IMO. Also some costume store have big closing sales and cash only. A Major one which ran for 70 years closed in the city few hours from I live missed it. People flocked to it it was cash only. I found when I was expecting so many family member did hand many baby items as babies grow so fast. I in turn handed/passed my children items to friends and other family members. I even OP Shop places like St Vinnies, Salvos etc which MF could have done which would not leave a paper trail as most except money.
