I have a Ravenswood shirt as well -- I don't know if you noticed, but I was wearing it when you met me. I've found that it helps to re-thread the ties on the cuffs, so that they make x's inside the sleeve, and cross-over ladder style outside. It takes up more length, and leaves less hanging loose. Or you can pick up some inexpensive shirt studs, and use them to close the cuffs -- if your shirt is like mine, you'll need a full set for each sleeve.

I do love the shirt. It's held up very well over the year and a half I've owned it.
