Barbara and Jenna Bush: Style Evolution (PHOTOS)

As former First Daughters, Barbara Pierce and Jenna Welch Bush have grown up in front of the cameras. The twins have always dressed in conservative ensembles and have gradually pushed the envelope while their father was still in office. Let's face it, you can't get away with showing too much skin without harsh criticism if you're the First Daughters of the United States.

Unlike other famous daughters, the twins aren’t resting on their laurels. Barbara, the older of the two, is the president and co-founder of Global Health Corps, a non-profit organization for public health. Her blond other-half is a teacher, writer, philanthropist and NBC correspondent. She also married Henry Chase Hager in 2008.

Take a look at Barbara and Jenna’s style in the gallery below as we celebrate their 30th birthday this Friday.
