If you'd be willing to try men's jerseys, check out the Nashbar & Performance men's sections, there are a few hi-vis and/or bright yellow long-sleeved jerseys there:

Team Cyclist & Colorado Cyclist both have a few bright yellow long sleeve jerseys for men (but not necessarily that weird "hi-viz" color). They might be more stylish.
