Today we plan to go to the new shopping complex in KL, The Pavalion with my cousin. Normally newly open shopping complex will get a lot of crowd and not to surprise finding car park is another nightmares, luckily we manage to find a parking nearby. Most of the shop already open, mostly are high class and branded brands like Aigner, Club Monaco, Coach, Ermenegildo Zegna, Hermes, Hugo Boss, Juicy Couture, Prada and Versace plus a Jaguar showroom. Wonder why it put a showroom in a shopping complex, could it be next time when friend ask what you had bought on your shopping? “nothing much, just bought a new jaguar” .
