@Avatarit Thank you. I give Carmen and Andreia their own style of attire and hairstyle. Also, Andreia has more weight which I intentionally did in CAS when I created her because I notice with some twins one is slightly bigger or one is slightly taller than the other. Carmen has been working out on her own accord so she's muscular and I usually have her wear glasses. Not sure about Carmen's style yet but she is currently wearing this.

Andreia has a punk rock look to her. But I'll probably go back to the other hairstyle.

Whenever I do figure out Carmen's style, it would be interesting to swap the twins style for a photoshoot. And I don't recall having them ever wear the same clothing and hairstyle so that would be fun too.
