Wow, thank you so much for the compliments, everyone! I'm glad the outfit and photos are such a hit. Now that the weather is nicer and I won't freeze to death, I really should try to take more outdoors outfit photos.
Mani, the pants cuff is pretty simple. Basically, I folded a big piece (like maybe 3"?) of cuff under inside the pants leg and then I take that and fold it up like a regular cuff. This exposes the folded under part instead of the white underside of the fabric. In this particular case, I then flipped the original hem back out (leaving all the folds in place) to make the cuff lay flatter.
