Reese Witherspoon's briefs are still ready for presentation ... as is her sick bikini bod.

Reese marked the 15th anniversary of "Legally Blonde" by slipping back into a bunch of her wardrobe from the flick ... and wisely included the bikini she wore during that Harvard essay scene.

Erection, your honor!

Sustained!

Seriously. 😂💖 #LegallyBlonde15
