I am going on a cruise on a small ship in December. We are going to Bosnia, Croatia and Montenegro. I have no idea how to pack. We leave the beginning of December and will return before Christmas. Can anyone help me out?
It can get down to freezing overnight, per one historical glance at www.wunderground.com/history/. Adjustable layers and a wind-&-rain-proof coat can be very versatile. At this time of year, the layers would include hat, gloves, scarf, and maybe some "performance" fabrics that can still be lightweight, such as silk long underwear, light fleece or merino wool sweater, warm socks and shoes. A heavy wool coat is not packing-friendly, though some down jackets are.

I was in Sarajevo and Mostar in mid December and the highs were in the 30's to low 40's and lows got into the teens. I lucked out with clear skies, but they got snow in the weeks after I left.
I usually wore a long sleeve t-shirt, sweater, jeans, sneakers so I was comfortable inside and then had a warm coat, gloves, hat and scarf outside (this was pretty much my uniform through Eastern Europe in December). Definitely take gloves, a warm hat, and a scarf. I took a scarf that could double as a head covering to go into mosques. I also recommend wearing shoes with some good traction like sneakers since rain, ice, and snow can be slippery.
Have a great trip. I loved Bosnia!
Seconding Stephanie's point about shoes with grippy soles. You'll probably be walking on a lot of wet cobblestones. Even if there's no ice, that can be very tricky, and it will be worse if you sprain an ankle.
