Another one who loves merino (I wouldn't wash it every time if I'm wearing it, as I'm wearing a bash layer underneath). Weirdly, my merino jumper dress does bobble 
. It's from Numph, nice style but on that basis I wouldn't recommend the quality or buy from them again. I also think the smooth nature of merino is flattering on those of us who don't want to bulk up our top halves.
I'm wondering about soap, now. I use shower gel, as our water is super hard and it can produce scum, nice. However, I did use to use french olive oil soap, which was lovely. I might look out for some.
banana with regards to moths, we had an infestation the summer before last. I think they come in from the garden, as it is shady and seems full of them in the summer months. They completely ate through a beautiful, Indian rug and the carpet in the living room. We cleared out the room and changed the carpet, I also got very good at killing them, it was much more effective than the pheromone strips! I put my out of season knitwear into a vacuum bag and weirdly, the only thing that was eaten was my toast jumper dress (sadly, one of my favourite things). Any moths I see in the house just get killed now, it seems to have stopped any further infestation but they are buggers. I don't put clothes I've worn back in the wardrobe either, only clean things as that apparently attracts them too, so any out of season stuff always gets washed/cleaned before storing.
