King James -- who is entering his 21st season -- clearly wanted to come up with a special look for the Los Angeles Lakers opening game against the Denver Nuggets at Ball Arena ... and he certainly didn't disappoint.

The 19-time All-Star forward is covered in Louis V ... from the $5k damoflage tweed chic collarless jacket and $1,250 pants to the $1,220 LV checker derby kicks.

He didn't stop there -- the Speedy Bandouliere 40 he's holding comes with an $11k price tag, and the briefcase will set the Average Joe back another $9,500.

So yeah, Bron's whole look is fit for a king.

BTW, some of those pieces LBJ is wearing are from Pharrell's men's Spring-Summer 2024 collection. The famous producer/rapper became the high-end brand's new men's creative director in February ... and debuted his items in Paris this summer.

James wasn't the only player showing up in style on Tuesday -- Michael Porter Jr. wore a signed Peyton Manning Broncos jersey ... and Peyton Watson was reppin' Deion Sanders with his own autographed "Coach Prime" gear.

High flyer Aaron Gordon also put his interesting taste on display ... going with a sleeveless burgundy blazer and shorts.

As for James' look ... anyone who wants to get their hands on the same items will have to wait just a bit -- pre-order sales start the first week of December.
