Flannel robe in white-out plaid

I love this robe! The flannel is great quality, and the details, such as the wider lapels and tie and the piping on the collar, pockets and cuffs, are spot on. The sizing, however, is weird. I always wear medium at J Crew, I'm 5'8", 145 lbs, and I ordered this robe in Small/Medium. The sleeves are REALLY short! Like, bracelet length short. (You can actually see this on the model in the picture.) I then tried on the Large/XL, and the whole thing was huge on me. So I decided to keep the S/M and embrace the shorter sleeves. But I'd prefer it if J Crew just made the full range of sizes, Small, Medium, large and XL.

My daughter is very happy with this robe and will wear it on Christmas morning. Its a lovely flannel and fits just perfectly in xs which she always buys at J.Crew.
