The first poem that comes to my mind in the context of Utena is this one:

William Blake wrote:

The Sick Rose

O Rose, thou art sick!
The Invisible worm,
That flies in the night,
In the howling storm,

Has found out thy bed
Of Crimson joy;
And his dark secret love
Does thy life destroy.

Our invisible worm here is Akio, or false princes, or the idea of adulthood, depending on your bent.

I know it's terribly typical, but Robert Frost's Stopping By Woods On A Snowy Evening seems to fit. I think that's more a statement on the ambiguity of the poem than the actual similarities, though.

Whose woods these are I think I know.
His house is in the village, though;
He will not see me stopping here
To watch his woods fill up with snow.

My little horse must think it's queer
To stop without a farmhouse near
Between the woods and frozen lake
The darkest evening of the year.

He gives his harness bells a shake
To ask if there's some mistake.
The only other sound's the sweep
Of easy wind and downy flake.

The woods are lovely, dark, and deep,
But I have promises to keep,
And miles to go before I sleep,
And miles to go before I sleep.

It reminds me of the whole final struggle with the promise to Dios to save Anthy and whatnot.

I was just revisiting Anne Sexton's work and thinking how much of Transformations, echoes against SKU quite nicely.

From "Briar Rose":

Briar Rose
was an insomniac...
She could not nap
or lie in sleep
without the court chemist
mixing her some knock-out drops
and never in the prince's presence.

From "Snow White and the Seven Dwarfs":

And thus Snow White became the prince's bride.
The wicked queen was invited to the wedding feast
and when she arrived there were
red-hot iron shoes,
in the manner of red-hot roller skates,
clamped upon her feet.
First your toes will smoke
and then your heels will turn black
and you will fry upward like a frog,
she was told.
And so she danced until she was dead,
a subterranean figure,
her tongue flicking in and out
like a gas jet.
Meanwhile Snow White held court,
rolling her china-blue doll eyes open and shut
and sometimes referring to her mirror
as women do.

Here's one that's popular in the UK that fits Utena pretty well.  It's also, IMHO, a beautifully constructed piece of lyricism.  We'll stick in some snarky commentary in white text to complete the effect.

If, Rudyard Kipling

If you can keep your head when all about you
Are losing theirs and blaming it on you,
[The story of Utena's life.]
If you can trust yourself when all men doubt you
But make allowance for their doubting too,
[I don't know if Utena understands self-doubt, but we'll give her a pass on this one.]
If you can wait and not be tired by waiting,
Or being lied about, don't deal in lies,
Or being hated, don't give way to hating,
And yet don't look too good, nor talk too wise:
[Utena looks fantastic, but otherwise she's a good fit; her nobility is characterized by its grace under pressure.  She's certainly got "nor talk to wise" going for her.]

If you can dream--and not make dreams your master, [Bingo.]
If you can think--and not make thoughts your aim; [Can Utena think?]
If you can meet with Triumph and Disaster
And treat those two impostors just the same; [She is the Energizer Bunny.]
If you can bear to hear the truth you've spoken
Twisted by knaves to make a trap for fools,
Or watch the things you gave your life to, broken,
And stoop and build 'em up with worn-out tools:
[The notion of a prince, torn down and built up again, is the story of the last arc.]

If you can make one heap of all your winnings
And risk it all on one turn of pitch-and-toss,
And lose, and start again at your beginnings
And never breathe a word about your loss;
[Episodes 11 and 12.]
If you can force your heart and nerve and sinew
To serve your turn long after they are gone,
And so hold on when there is nothing in you
Except the Will which says to them: "Hold on!"
[Episode 39.]

If you can talk with crowds and keep your virtue, [I would if I had nipples!]
Or walk with kings--nor lose the common touch, [Wakaba is actually frustrated by Utena's success in this, I think.]
If neither foes nor loving friends can hurt you; [Stab me in the back?  I open your coffin!]
If all men count with you, but none too much, [Actually, I do worry about codependence in Utena's future.]
If you can fill the unforgiving minute
With sixty seconds' worth of distance run,
Yours is the Earth and everything that's in it,
And--which is more--you'll be a Man, my son! [That's "Prince," Rudyard.]

hay, that's my high school graduation speech!  minus the last line...

anyway, for Shiori x Juri
Who, if i cried out, would hear me among the angels' hierarchies?  and even if one of them pressed me suddenly against his heart: i would be consumed in that overwhelming existence.  For beauty is nothing but the beginning of terror, which we are still just able to endure, and we are so awed because it serenely disdains to annihilate us.  every angel is terrifying.
