Who: Ashlee and Jessica Simpson.
What: The blonde sisters teamed up to promote their joint fashion venture, Jessica Simpson Girls, at Macy's, and both girls opted for completely different looks. While Jessica was pretty in a star-print shirt, nude nails, and tumbling waves, Ashlee went a little edgier with a quiff hairdo, black nails, and burgundy and black metallic skinny jeans.
Where: Costa Mesa, California, 10 November.
Verdict? Jessica looks fantastic after losing 60lbs since giving birth to daughter Maxwell five months ago, but we also like Ashlee's rockier look. Tough one. What do you think? Let us know below, and see more beautiful blondes here:
