Del Potro's 2015 sydney tshirt

Hi guys! First post here..

I just have a quick one. I'm looking for info about this awesome tshirt which Delpo dressed during the Sydney tourament in 2015:



If it's possible I would like to know about the whole outfit info (name of collection, etc) because I could not find any more information. Thanks!

PS: Please forgive my english, I'm still practicing it .. hehe
