Red Hot! Pippa Middleton Wows in a Raspberry Dress at Friend's Wedding

Kate Middleton's sister looked stunning in a fitted frock as she attended the nuptials of a close friend this weekend

When it comes to wedding fashion, Pippa Middleton sure knows how to turn heads.

The 28-year-old party planner looked stunning in a tight-fitting, raspberry-hued Issa silk dress, paired with a matching fascinator and black pumps as she made her way to longtime friend Camilla Hook's wedding. Hook tied the knot with Sam Holland in East Lothian, Scotland, Saturday, according to the Daily Mail.

And if this dress looks familiar, your mind isn't playing tricks on you.

Pippa's big sis, Kate Middleton, wore the blue version of the jersey dress back in November 2010 when she announced her engagement to Prince William.

Perhaps a sisterly "who wore it best" is in order?

Check out Kate's version and sound off in the comments.
