There have been quite a few people asking questions about the Crombie shirts, so I will do my best to provide as much information as I can tell from the shirts I purchased. Shirts feature split back yoke, butterfly gusset, mother of pearl buttons, and cross-stiched buttons. The shirt does not have single needle tailoring though, which was dissappointing as the shirts are valued at 70 pounds each. I purchased a 15" collar, which was slightly oversized. Also the sleeves measured 34.5" Unfortunently, Crombie doesn't offer multiple sizes in their shirts, so I am going to have to return mine, as it is too small. If anybody has any other questions, just let me know.
