Well since I nominated her I might as well put some defenses for her.

Peach is a lot stronger than she looks, while she's not as physically strong as DK or the Mario Bros. her strength is not to be underestimated, actually it probably will be given that she's a skinny girl but she does have superhuman strength way beyond normal humans.

She can lift up boulder enemies above her head and throw them with ease.

She Team Rocket'd Bowser just by smacking him with her parasol.

She can defeat metal clad minions of Smithy just by slapping them, and there's gorilla enemies that even look like DK that she can kill with her physical attacks alone. A normal human stands no chance against a gorilla but Peach can just slap these brutes away.

DK is definitely not going to shrug off her attacks if Bowser can't.

She's a lot more durable than she looks as well even without lazy shell. She tanks all sort of blades, beams, boulders, elemental magic, cannonballs and missiles ect in Mario RPG. I doubt DK would be able to one shot her consider what she endured fighting Smithy and Count Bleck's army as well as fighting Bowser directly in Super Princess Peach. If Bowser can't one shot her even as giant then no way DK can. And being able to heal herself is a cherry on top.

Peach is also almost as nimble as Mario and Luigi as shown in Mario 3D World, while she's not as fast as them DK has had trouble landing blows on Mario before just because of how agile he is, and what Peach lacks in speed she can make up by floating, or using a cat suit if that's allowed.

And Psych Bomb is another tip in her favor. Mario has beaten Donkey Kong with bombs before, why not Peach as well?

And the kicker is that Peach doesn't have to wait for DK to throw bombs, she can chuck them anytime she wants (as long as she has enough FP)

Though I think fight comes down more to how Peach feels since this is the same Peach that gets captured over and over again. Though if she does get agitated enough she's not afraid to scold the Mario Bros. to get out of her way.

I guess one advantage that DK has is that Peach can't understand his language so she won't know if DK insults her.
