They may shy away from expressing themselves creatively. Traditional denotes a respect for age-old customs and a preference for familiar, classic styling. On the other hand, conservative refers to a reluctance to break the mold, which can be limiting in terms of artistic expression. Finally, conformist is used to describe someone who is keen on fitting in with what is considered the norm, whether that's in terms of fashion or social values.
