Surely something can be done to keep wardrobe costs down. They could wear the same clothes from time to time. People really do that in real life, lol. Perhaps sell the clothes when the actors are through wearing them. I'm sure they would sell in an online store. Have a sponsor provide clothes. Plenty of clothing designers would love to have the advertisement. I've always looked to the soaps for my own wardrobe ideas.
I've long thought there should be more product placement in the shows. You could base story lines around ads. Build them into the stories. It can be done and well, with the right writers and the soaps have them I do believe. It's the original format for these shows.
Another thought, have an online store that not only sells clothes but perhaps Bo's coffee cup, Nora's briefcase, Natalie's necklace, etc.
These are a few of my thoughts. Maybe it should be another post, haha. In any case there is an undeniable market here.
