TRAVIS SCOTTNEW COLLECTION WITH DIOR ...This One's for Pop Smoke!!!

Travis Scott's releasing another collab outside of the music biz ... but this one includes a tribute to his friend and fallen hip-hop star, Pop Smoke.

The rapper's Cactus Jack brand has entered a partnership with the popular French fashion house, Dior -- which is also the name of a popular Smoke track -- and Travis revealed the first item in the collection is all about Pop.

It's a t-shirt with the late rapper's face emblazoned a little off-center on the front ... with lyrics from his song on the back. Travis wrote, "U CANT SAY POP AND FORGET THE SMOKE. NOW U IN ALL THE STORES 4 EVER."
