Correct, but considering TS' reasons for removing the size charts, that's the only other explanation. As an aside, I've dealt with buyers who have no idea about their measurements beyond "I wear size Medium in GAP/Uniqlo/JCrew."
Can anyone share their experiences with Gustin shirt sizing? I wear a Medium in Uniqlo/GAP shirts, but the Gustin measurements I've seen in SF/eBay listings are different from Gustin's fit guide (e.g. Slim Large = 21.5" chest / 18" shoulder vs. fit guide's 19" shoulder).
My measurements: 22" chest / 18.5" shoulder / 40-41" waist / 15.5-16" collar
