Well I got them late Monday and was able to try one on last night. I purchased the XL and it
just fits me. The sleeves are a smidgeon too short but not excessively so. They got the upper arms correct in that there is no bunching up or binding with full cross-arm motions, although the elbows could’ve used a little larger pocket that I will likely get modified. Plenty of arming point locations and arming points provided, though as surmised earlier, they will require leather tab reinforcements prior to attaching armor. I had gained back some of the weight I loss in getting ready for Longpoint so when I lose that few extra pounds this doublet will fit even better.
All in all a good purchase for a basic doublet for getting measurements for later period armor orders…yes I’m preparing to migrate to the 15th century!
