It seems Camila Alves, Matthew McConaughey's soon-to-be baby mama, has been up to a bit more than kitting-out the nursery. The Brazilian model has teamed with her mother on a line of handcrafted leather bags that are roomy enough to accommodate a laptop and other globetrotting miscellany without veering into schleppy territory. Named MUXO ("goddess of the water in an African legend," according to the mymuxo.com Web site), priced from $650 to $1450 and slated for Kitson, the styles are themed around Alves's various haunts. But the one common denominator among the LAX, the Malibu, the SoHo and the Little West 12th? Lots of groovy, free-spirited fringe.
