Rebecca Judd has a passion for fashion.

And on Monday, the AFL WAG looked as chic as ever as she caught a train to a cricket game with her son Oscar.

The 39-year-old made a style statement in a white shirt and matching coloured pants for the outing.

Rebecca completed her stylish look with a pair of white comfortable sneakers and a crossbody bag.

She left her long brunette locks out and appeared to be wearing a neutral palette of makeup.

It comes after Rebecca celebrated Christmas with her family on Sunday and shared a glimpse inside her intimate shindig with her fans.

In an Instagram post on Christmas Day, the WAG posed alongside her husband Chris Judd and their four children.

The Jaggad activewear owner and her AFL star husband share Oscar, 10, daughter Billie, eight, and twin boys Darcy and Tom, four.

The family had Christmas at home, tucking into a a seafood feast and a delicious pavlova.

The family also took part in a game of tennis on the private court at their Melbourne mansion.

Rebecca and her brood live in a $7.3million mansion.

The Brighton home has a gym, a tennis court that can be turned into 'a footy oval or cricket pitch', and a magnesium salt pool.
