Wearstler, whose flagship boutique is at 8440 Melrose Ave. at North Croft, is known for her creative clothing, accessory and interior designs. Now Wearstler blogs that she fashioned a Halloween costume for her son’s birthday party that she describes as “alien with baby complete with intergalactic beehive.” And in case you’re wondering, that little ghoul isn’t her little boy.
