This season's theme is "1950s Post-War European Dress," and from the BLACK COLLECTION inspired by black-and-white films, this styling uses the BASEBALL T-SHIRT - PIGMENT/
Personally, I'm not used to wearing black items, but using similar colors overall creates a sense of unity, so I recommend it for those who aren't used to wearing black.
Of course, it also pairs great with basic items like military pants and chinos, so be sure to try out the BASEBALL T-SHIRT - PIGMEN, which looks great on its own.
