Teresa Giudice might be serving time behind bars, but that hasn't stopped the Real Housewives of New Jersery star from spending quality time with her family -- and looking surprisingly stylish.

A photo of the Bravo star has turned up showing Teresa posing for a family photo with her husband Joe and their four daughters, Gia, Gabriella, Milania, and Audriana. While Teresa is decked out in head-to-toe prison green, she still pulls off a slight smile.

Sources tell ET that the photo was taken on Mother's Day, and it looks like the 43-year-old RHONJ star's loved ones dressed up for the special visit.

Teresa even managed to pull the prison look off. While she might not be dripping with jewelry, sources say she's worked on maintaining her appearance with hair and nail care.

According to sources, the girls were "thrilled" to see their mom, and when the family is able to visit Teresa they all catch up on what the girls have been up to and the family often takes many photos together.

Teresa is six months into her 15-month prison sentence for fraud, but may be released in December. At some point following her release, Joe is expected to begin his 41-month prison sentence.

The couple took a plea that would allow them to serve time separately so that one of them would be able to care for their children.

It seems that Teresa is making the most of her time behind bars. A source tells ET Teresa is keeping a journal that she will use to write her memoirs and is keeping a record of what her time in prison is like, in order to write a book when she gets out, which might help the couple cover the $414,000 in restitution the couple was ordered to pay.
