“[...]sizing info does not match tag”

“[...]sizing doesn't match the tags. I ordered a 52 EU, which [...]pegged at 46 US. The tag says 52 EU and 42 US. That said, I normally wear a 45L with an 8 drop (large shoulders), and this coat fits well but for the sleeves, which are just a bit too short. There's about 1" of extra fabric in the sleeve, and I'm hoping my tailor can let at least 3/4" out to make the sleeves long enough. Nice finishes throughout, though the 'Made in Austria' tag is glued on and arrived loose at one end”
