grand theft auto

I was watching some gta 5 gameplay and heard that you could buy some gang clothes for Franklin. He is in the gang called the "Families". But I couldn't find any good gang clothes for him. All I saw was a green cap and a green tank top. Also I heard you could get a gang haircut. What in the world is that? And I did see a few gang families tattoos. So what does your Franklin look like? Any suggestions? Thx for any answers, comments, and responses!
