I know one wears a Kapoteh on Shabbos, Yom Tov, Chol Hamoed, and 19th of Kislev. What other times is it Minhag Chabad to wear a Kapoteh? 10 of Shevat? 12 and 13 of Tammuz? Rosh Chodesh Kislev? Bris Milah? Father of Chosson/Kallah at wedding? Hachnasas Sefer Torah?
There is no formal Chabad custom about most of the days you have mentioned. This is an individual choice which can and should be discussed with one’s personal Mashpia.
The only exception is wearing Shabbos clothing at a child’s wedding or at a child’s Bar Mitzvah. This is something clearly mentioned in Poskim.
