"They tried on sunglasses for over a half an hour," an onlooker tells PEOPLE, adding that they also checked out handbags and customized Havaianas. "Casper bought Jennifer a pair of the newest Brian Atwood stingray shoes and L.A. purchased his wife Erica a Tori Praver bathing suit."
Free from any security guards, the large group also headed across the street to the original Blue &Cream store, where Casper purchased some Oliver Peoples shades, and his lady love bought a pair from Stella McCartney.
"The [store] locked the doors for this shopping spree," the source says. "Onlookers sat outside and tried to get a glimpse of [Jennifer]."
