Lost!

I see nothing wrong with "sitting on" as a come-along-with-me through time option. Clothes are doing nothing but touching you in various places, and are as inanimate as a piece of wood or fiberglass.

We may bemoan the lack of scientifically and visually more satisfying TTW nakedness, but once clothes are along for the ride - well, in for a penny, in for a pound. Outriggers, passenger jets, it's all good.
