The jersey length looks like it might be fine on me, but it's hard to tell. The sleeves do look weird though, like they would chafe right at the front of the armpit. Maybe the sleeveless one would work better, though?

And the presta skirt...hahahaha I'd look like a peacock with that thing on. The last thing I want to do is hide a padded behind with lots of ruffles and extra volume!!
