I live aboard on a 30 footer in the UK. For clothes storage, I converted the hanging locker into a space I could put plastic storage boxes with lids into. Also, under the V berth infill space. My clothes in the boxes always seem to stay nice and dry. A mixture of larger boxes for trousers, T shirts, pullovers, etc., and smaller ones for underwear and socks means that all available space is used. Stuff that is to go to the laundry lives in a couple of those large canvas
'bag for life' type shopping
bags and that is in a much smaller former wet locker next to the companionway
From September through to April, I run a desiccant dehumidifier and this keeps the boat nice and dry. Every boat is individual, so you might need to get a bit creative as to where you find the space, and in particular space that is easily accessed without needing to lift
and so on.
