Brandon Jennings: Talks NBA Fashion ... In $300 Sandals

NBA star Brandon Jennings has opinions about the league's new policy allowing corporate logos on team jerseys ... and he was more than happy to talk to TMZ Sports about them.

That's all well and good ... but we were way more impressed with what Brandon was wearing as he did the talking ... a $300 PAIR OF GUCCI SANDALS.

He pointed them out and we looked 'em up ... they're called "GG Caleidos" and they retail for around $280. He's basically wearing your PlayStation 4 on his feet.

Check out the clip -- Brandon was leaving Crustacean in Beverly Hills when we had the convo ... and he was eloquent ... but damn, bro ... $300 dollars??!!!

Points for rocking the flip flops ... but EXTRA POINTS for rocking them with socks ... SWAG.
