Reebok Les Mills Clothing

Hello everyone! I’ve doing some Les Mills Body Combat and Body Pump at World Gym and I’ve seen many people using this:™-tank/BQ5178.html

I’ve trying to find one in Taipei, but the Reebok retailer told me that they don’t have this item. So, I’m wondering where can I buy one of this or where can I buy Les Mills clothing in Taipei. I will be very pleased if someone can give some addresses or FB pages where to buy. Thank you, everyone!
