I do a good deal of commission work for menswear, so here are a few things that might be helpful.
Trent's waist is too small for a Numina man, so you have to compromise on the fit, and make the waistline a bit looser. If you're doing a dress shirt which is tucked in, it's not noticeable. Make the hems on the long side, and that, combined with a bit of hidden elastic, will allow the Jamieshow men to share.
If you really want to sell menswear, the Kinsmen/ Tonner Matt size is more in demand.
I also do well with the Tonner Athletic body size, which also fits the original Kinsmen Garrett and Booth.
