Kim Kardashian is in her Elle Woods era ... a prospective lawyer sporting some blonde curls!

The reality star and fashion mogul shared a series of steamy hot pics to her Instagram ... sporting a trench coat that showed off her ample chest, thick black sunglasses and short blonde hair that barely touched her slender shoulders.

Waiting for your permission to load the Instagram Media.

The star flashed a pair of peace signs and some duck lips for the camera during the shoot ... looking effortlessly glamorous as always.

She captioned the pics with a simple "✨" ... not needing a single word -- because the pics spoke volumes.

Kim's gone blonde before ... but usually keeps her hair long when she does -- though it looks like she's got her summer cut before the solstice.

BTW, this is a very recent change ... remember, Kim belted out songs at Ariana Grande's Los Angeles concert with Emma Roberts just last week -- and she still had her normal dark locks.

She looked to be having a ball at the show ... but maybe she heard blondes have more fun???
