I had a question a few months about about CAS and clothing options. I am STILL getting different lists of clothing options for different sims!  I'm NOT talking about ages either. I keep that set at false because I find that hair, clothes etc never fit the other ages/genders right and often looks weird. (excpet adut and YA, which basically stay the same anyway, except a few of the outerwear coats) 
It seems that sims get a few other types of selections of clothing than other sims get. I have double and triple checked my settings too!  I don't have any of them condensend except Hats and Accessories and I have "show hidden objects" as true.
Almost every time I dress a sim it's under CAS using MC cheats or the MC Cheat Styling option. But CAS gets used more because often I'm altering sims who've aged up and I like to double check traits and stuff while I'm at it.
Anyway, there are STILL clothes I get for some sims that don't appear for others!  Why?    Based on what I'm seeing sometimes it does seem that it depends on the career the sim has, but the thing is that the different clothes don't always just appear under the career tab or outfit tab. I just don't understand why I don't get the same list of clothes for every sim!  Again, I'm not speaking of the age difference clothes. I hope I'm making sense here. I can use a random example, but the clothing is just an example and not nessessairly what is or is not appearing. It's all kinds of styles.  Okay so, under everyday wear I dress Sim A. Sim A is an adult male and he gets the usual list of everyday clothing, but he also has a polo shirt in red, blue and green and some kind of Asian sytle shirt in black, blue and deep red,  but then I go to dress Sim B who is also an adult male and he doesn't get the Asian style shirt as an option and his polo shirts have different symbols on them.  Is something off here or is this just the way it's supposed to be? There are some outfits I really like that I'd like to have other sims wear. Like I can't always get the Tuxedo with tails to appear under every sims formal wear, but it does appear for some. And for the record the clothing I'm talking about is ALL EA STUFF. I always see the few custom content items I have for every sim.

With MC you can also transfer clothing from one sim to another, as well as copy clothing from one category to another on the same sim. I don't have a good answer to why the clothes differ for your sims, but thought MC might provide the workaround at least.

WoolySmurf - I will look into that. Wish someone knew what was going on here. But it's not a huge deal if I can transfer clothing. I don't know how, but I am sure I can figure it all out. 

'Copy Clothing Between Categories' and 'Transfer Clothing' are both under Intermediate if you click on a sim. Under Basic you also have Remove Clothing which is useful for deleting unwanted outfits. They're all quite straight forward to use if you're familiar with MC in general.
