Plus Size Mamas - Best Place for Maternity Clothes

Ho
Hi ladies!  I'm 5'10" and usually wear a size 18 or 16W in jeans.  Sometimes I can shop at regular stores, and sometimes plus size stores.  I'm right in between.  Can you recommend the best stores to shop for maternity clothes?  I'd prefer a physical store to buying stuff online, so I can try it on first.  I'm in Southern CA.  Thanks!!
