Last Spring, Hunter Wellies were hot sellers.  And it appears they are still going to be hot this coming Spring as well, as they were seen on Nicole Richie, out with daughter Harlow, on February 6th, 2009.

Original Hunter Green Wellington Rain Boots are available in an array of colors (green, orange, wine, navy, brown, black, silver and yellow) from Jildor Shoes, $115.

It seems that Mary-Kate Olsen always is in the limelight, so thought we should show Ashley Olsen some love.  Above she is seen wearing  Siwy Camilla Cut Off Denim Shorts in Wonder (also seen on Nicole Richie), available from Singer22.com, $158.

Rumors have been swirling about Nicole Richie starting a maternity clothing line, a baby line, and even a jewelry line.  Wonder if she’ll add jeans to the list? Nicole has been seen wearing Paige Premium Denim Laurel Canyon Bootcut Jeans, (available from Tobi.com, $179) a lot lately, which I think are way more becoming on her than her signature skinny jeans.
