I agree about Target, TJ, and yes Ross, where I found a couple of items for my last trip (back day before yesterday). Cheapies and then toss (the whites at least).

Don't know yer age and style, but the items I found most useful on this trip (weather in Venice was HOT and humid) were washable silk -- black pants and black top with 3/4 sleeves. For night, a silky cami works, for day, a casual tank works. Also brought a reversible and very lightweight black/white print skirt and white linen-blend camp shirt. Everything went with everything. Also a couple of JJills tops--the pucker Ts in mocha and black. I brought 2 pairs of sandals (one SAS and one Teva) and a pair of walking shoes. Probably you want closed toe shoes at Pamplona!
