There are many chic people in the airport. They wear something casual but chic.
One of the must have items I love the most is Birkenstock. Birkenstock is really popular in HK. I love it not because of its popularity, but the simple and durable. Basically, you can easily do mix and match. The suede one is a classic one.
What is the best pair of shoes when you get on board? For me, flip flop or Birkenstock XD
