Jen, we were on this tour sep 28-oct 7. Here is my thoughts - bring a pair of capris, forget the shorts. Capris are good for warm days but nights come quick and are still cool. Also, the big cities you visit, capris are not always the fashion choice if locals. Good for the coast or hot rural areas. Jeans are still a universal pant, bring nice ones and pair with black tops for evening, with scarves and a few bangles for a nights "out". A rain jacket is essential, it rained in Poland and Croatia, Krakow was quite damp when we were there, but oh so lovely!!!!! I brought a couple dresses, and never wore them. I did bring leggings and longer style tops and also a jean skirt with black tights and wore them out!! I brought sandals, sturdy type and wished I hadn't. I could have used a pair of nice flats instead and had them for evenings. Walking through the day required good walking shoes, but the evenings when you had dinner or a play or just sitting In a square having a drink, I wished I had nicer flats to wear, other than sturdy shoes and runners. Some on our tour had clothing you could wash in the sink, while handy to do that in a few places, we did laundry at laundrymats instead. However, after Budapest, there is no Opportunity for that, so sink washing was handy. The weather can be guessed but not predicted. Layers , black, jeans, skirts, leggings, clothing by FIG, all work well. Good luck and let us know how it went. Was a wonderful trip for us!
