There was a lawsuit but she never went bankrupt. The company they took the bussiness loan from was taken over by a new company and they wanted the whole loan repaid and gave B&E a deadline, which wasn't possible as it is hard to pay so much money in a short time. The new company used Jessica's name to pressure them to pay back faster and that hurt her reputation even though it wasn't a personal loan. The issue was resolved so I don't think there's any need to bring it up especially considering how well B&E is doing now.
It is true that designers send idols their clothes and Jessica does too but that is only when a new collection drops. She can't possibly send Pr packages to every artist active in the industry. Also a lot of her popular pieces are often sold out.
