I would stay away from the Commerce one. They are not outlet stores. You might as well go to the mall and pay the full price. I do not see any sales there. The Barstow one which is a couple of hours away have a couple outlet malls therer.
The only outlet center within a short drive is the Citadel Outlet center. Just take I-5 to Commerce.The others in the area, such as Camarillo, Cabazon (my favorite), and Barstow/Lenwood (my second fav), are a bit of a drive. Since you ll be in the area, why not check out Santee Alley for deals? It s downtown, south of Olympic between Maple and Santee. Check out fashiondistrict.org for more info.
The Citadel Outlets in Commerce are the only outlet stores in LA. http://www.citadeloutlets.com/It should take you about 20-25 minutes to get there from the Hollywood area without any major traffic. The outlets are about 15 miles from the Hollywood area.
