New parents, Gavin Rossdale and Gwen Stefani, hit the red carpet last Wednesday on a night out in London.  Gwen seems to be letting her hair grow and is wearing it as platinum as ever.   This formal style appears old-fashioned and though a compliment to the dress she is wearing, it is not the fashion usually favored by Ms. Stefani.  The conservative updo is a simple fashion statement to be mimicked by shy women everywhere.
