This is been one of my complaints for ages about Hallmark, not specifically the anachronisms but the fact that all the damn characters look the same -- long, flowy, wavy-but-not-curly hair, heavy make-up, trendy but safe and generic clothing styles, etc. All the homes are McMansions with tasteful, bland decor, all the Christmas decorating is in red and gold, bows and glassware and greenery, with not a single homemade ornament or non-generically WASPy item in sight. Nothing wrong with any of this, of course, but when it's the only style shown it's so Stepfordy.
Anyone remember Cloudy with a Chance of Love (stupid title)? It stood out for me in part because the heroine's style was actually different, and appropriate for a grad student -- pony tail (the non-glamorous kind), nerdy glasses, more realistic clothing. There was the dreaded makeover, but if I recall correctly she didn't maintain that style.
