They are the same company but different price point. It is geared towards teens and also the comfort level is not quite as the steve maddens. It definitely wears out faster. It looks great and good if you don't wear them quite often.
Hi Jamie C. No Steve Madden Girl is a separate line to Steve Madden. It's aimed a younger women but the items are nice and definitely can be worn by women of all ages. The prices also tend to be a bit more affordable than the main Steve Madden line.
Think of madden girl as Steve's little sister. It is the same company but a different line geared for Tweens or women in their 20's. The style is still great and usually madden girl is less expensive without losing its great quality.
