The one that +Lefebvre is wearing is probably not what OP had in mind. I had a bad experience with excessively lacey surplices at STAS -- it was mostly the future SSJ crowd that was very big into these. We're talking lacey to the point of looking like women's lingerie, not what +Lefebvre was wearing.
OP here and yes, that's right, the one that Lefebvre is wearing in the first photo actually looks fine.
The one he's wearing in the second photo, and the ones even St. Pius X himself is wearing, I'm sorry, but those look effeminate.
I don't think recognizing this is a sin or "bad." I think it was in the McHugh and Callan moral theology book that I read that one might dislike and object to religious art because not all religious/sacred art is well made or "good" looking, so this may seem to be similar, in my view.
I don't like this sort of brain-washing where men look at flowery lace and say "yeah that looks so manly" simply because a Saint or someone highly regarded would wear it.
A black cassock, on the other hand, looks very good and manly, in my mind. The world seems to think so too, since this is the outfit they gave Neo in the Matrix movies (not endorsing or approving of them in any way).
