Although I crush hard on human Rainbow Dash, I like the version with this less revealing outfit better! But of the versions posted here, only the underwear versions have the background that would make for a proper ‘scene’.
 
I could get around this, though I’ve only got baseline Windows art programs on my computer. I’d use dozens of tiny, precisely lined up copy/paste actions to add clothes without disrupting the background. I’d then blow up the picture and use brush tools to smooth out any jagged edges. I’ve done that once or twice before; all it takes is patience. But more than I can usually provide.

This is probably just her very revealing sports outfit she wears underneath, and not underwear:  

 
Or it might actually be her underwear, and they’re playing some sort of strip football.

Probably someone who makes an edit

Any chance there could be a safe version of this? I’d love to be able to post it somewhere like on Facebook like “OoOoOoOh, look at me, getting all fit & such for the Spring!”
