I find this so hard. I'll be in a coastal town for one week and only want to take carry on luggage (back pack and small case - compliant with Ryan Air limitations).
I will wear jeans and a jumper, sneakers and my winter jacket on the plane.
I need to manage something that can also be worn to a church service but that for a couple of hours so I resent the space it takes up in my luggage.
There'll be no clubbing or requirements for smart evenings out. But we will eat out occasionally in relaxed restaurants.
