I love this. FANTASTIC WORK! (And...it rhymes. You're so good at rhyming...^^) I love the message in this. Keep writing your beautiful poems!

Anything where you rhyme "**" with "glass" is great.
Seriously though, I really enjoyed this one, not only in its semantic aspect but in that it preaches self acceptance. I, having seen a great many girls destroyed by trying to fit a social mold, find a poem like this a breath of fresh air.
The only improvement I would suggest is to play with capitalization. Not every line needs capitalizing. If you capitalize some and not others, you can place emphasis and accentuate your points. It's just one more way the poem can communicate to the reader.

Wow... This has an awsome message. I am still so impressed with your rythm. It's just so relieving to hear nice rhythm with rhymes like that. I guess it's a "pet-peeve" of mine... But no! You're awsome. And I love this poem! If you've got it, flaunt it! There are all kinda of shapes out there, who wants to be the same? I'm 5'0", stick skinny, and I wish so badly that I could be like those 5'4" curvy girls *sighs*... But hey! What's on the outside doesn't matter, and there's always someone for ya! =P

I love this poem! Very good work. . .everyone needs to hear this message.

i constantly struggle with accepting my looks and weight.

Wow! Too true! Amazing. A wonderful point! I loved the 'you're tough and determind/with attitude too' lines! Awsome!
