Chazon Ish was against short sleeves and whenever someone with short sleeves goes to Rav Chaim Kanievsky he asks them if they don’t have enough money to buy long sleeves. This is based on the Mishna Berurah who seems to say (somewhere in the beginning of Siman Beis) that short sleeves for men are not tznius because most people have it covered. The Minhag is not like this because Bzman Hazeh many men go with there elbows uncovered. And yes it is true that Rav Moshe went with short sleeves.
