A European summer is warm rather than hot in most of the continent, and the evenings are cooler than visitors expect. That single fact drives the list: one light layer you can carry all day matters more than an extra t-shirt.
Southern Europe in July and August is genuinely hot, and inland cities such as Seville, Rome and Athens are hotter than the coast. Northern and central Europe are milder, and the evenings drop enough after sunset that a light layer earns its place in a day bag.
The practical consequence is that you are packing for two temperatures on the same day, not one. That is the difference between a European summer list and a beach list.
Running the packing tool for ten days of warm-weather city travel produces the following. Set your own dates and destination for a list that accounts for the group and the activities you have planned.
That comes to 24 items and roughly 14 litres packed. Your own list will differ once you set the group size, activities and destination — this is the shape of it, not a fixed answer.

Churches and religious sites across Italy, Spain, Portugal and Greece expect covered shoulders and knees, and they enforce it at the door in the places you most want to visit. A light scarf or a pair of long trousers solves it for the whole trip.
Light breathable clothing for the day, one warm layer for the evening, comfortable walking shoes, a universal adapter, and sun protection. Southern Europe in July is genuinely hot; northern Europe rarely is.
A light one, yes. Evenings in northern and central Europe drop noticeably after sunset, and air conditioning on trains and in museums is often aggressive.
One pair of comfortable walking shoes you have already broken in. European city days involve far more walking on hard, uneven surfaces than most people are used to, and cobbles are unkind to thin soles.
Yes. Most of continental Europe uses Type C or F sockets at 230V, and the UK and Ireland use Type G. A universal adapter covers both, which matters if your trip crosses the Channel.
Comfortably, for most trip lengths. Summer clothing is low volume, and doing laundry once mid-trip removes the need to pack a fresh outfit for every day.
