Seliah mentioned a couple of things earlier that I'll co-sign. Morphs and ethnic characters. Unfortunately the official morphs have a pretty limited range so they stop before I get to where I'm going. More range might help in dialing in certain ethnic features.
Also suits. I was going to create a male suit rant/thread but I'll just go off here instead. They say males don't have a lot of clothes but one thing we do have is suits. Double breasted, single breasted, beautifully tailored Armani suits (saw one in a store, lol), thrift shop, hipster sport coats. Three piece suits, two piece and sport coats. Those long suits that some entertainers wear, and so forth. Along with that are various fabrics depending on the season and various shirts, collars and ties worn beneath. How about cuff links? Did I mention that adding a morph to open or close the lapel or put your hands in your pocket would be nice. OK, I know I don't ask for much, lol, but it boggles the mind how few suits are available for each male figure considering how many variations of the same female essentials have been released to the market.
