Packing

Hey, I was wondering if anyone could help me. I recently bought a small rucksack for going home at weekend but I also need to use it for short trips to Europe, like 4-5 days. The woman in the shop said it was definitely big enough but I'm having trouble fitting everything in. I've never really travelled with a luggage limit before so I'm sure I could manage without half the stuff I'm bringing.

What do you realistically need for 4-5 nights away? I'd bring 2-3 other pairs of trousers, about 3 tops for under a sweater, 2 sweaters, a dressy top, maybe smart shoes, essential toileteries, pyjamas. I could probably manage with less but I don't want to be struggling and wishing I'd brought more. Did I forget anything important?

I always roll everything but it doesn't seem to be helping much. Yeah actually I remembered the towel, just forgot to write it
