Yeah, your translation works better. Don’t know what I was thinking.

I don’t know why, but I always think that Pinkie should have a small paunch or some love handles. I know she is hyper active and does exercise, but all those sweets and pastries she eats should show somewhere. ^^  
Otherwise a very cute image and I love the anime style.

I think that one line says ノンワイヤーでもスポーツブラでもなんでも着るよ！  
So that’s katakana for “non-wire”, i.e. non-wired bras. The handwriting isn’t the most neat though.  
That would make the line “She’ll wear anything, from non-wired to sports bras!”

I think it’s nice, but it would be better if highlighted in another way than just round parentheses, because it’s hard to tell what’s the translation and what’s the comment.

Good translating, but next time, just translate. The things you said on the side with each post got annoying and unnecessary after while.

I’m down to the last one. FINALLY! Ten American dollars and a beer says that most of this is about Pinkies’ pies. (Her O-ppais!)
 
Alright, let’s get to it.
 
Translation:  
Her body is probably the most delicate. (Lit: I wonder if she has the most delicate body?)  
(Wouldn’t you know? You said earlier that Fluttershy was the softest of the bunch)  
(My dictionary (and internet searches) also brings up “Slender,” “Luxurious,” and “Pompous.” Since we aren’t using kanji, we can only guess from context.)
 
Her underwear is cute, but she is okay with anything!
 
It’s not clear, but she may even like to wear sports bras.
 
However, quite often she goes out WITHOUT A BRA! (Lit: There is a lot of NO BRA TIME!)
 
(Okay, there was no DIRECT mention of her boobs, but the fact that every line was about what held them in place and in one instance implied that she loves to let them swing free is close enough for me. You can keep your ten dollars, I just take the beer.)
