A stupid, overrated, and highly expensive clothing store most teenaged girls, even little girls and mid-aged women wear. Most of the clothing isn't even nice, and tons of young girls beg their parents to buy them a "lulu" sweater just to be cool and the same as everyone else.
Daughter "Can I please get a lululemon sweater! I want to be just like my friends!"
Mom "Of course you can, because being like everyone else is really cool!"
