have Trent but I am always on the look out for 16" male clothing.
One thing that would help me, and I suspect a good many other collectors too, would be to have separates. Things like Hawaiian shirts and casual shirts (especially short sleeved) fitted to Trent will also work for a wider range of 16" guys (and thus hopefully increase the market), whereas Trent's waist size and leg length is very different...possibly unique!
