Rashi
ואת פארי המגבעות means the beauty of the high caps — this is equivalent to: the beautiful high caps.
Chizkuni
פארי המגבעות, “the decorated turbans;” Rav Hai Gaon explains that the word means something that looks like an ornament in the shape of a pomegranate on top of the headgear.
Siftei Chakhamim
The splendid turbans. Rashi needed to explain this so we will not mistakenly think that פארי means as it does in, “He will cut the branches ( פארה ) with terror” (Yeshaya 10:33). Thus Rashi explains that it means, “The splendor of the turbans.” פארי is the plural of פאר , and means the same as פארים (splendors). Rashi says, “The splendid turbans,” because if the turbans were not splendid, there would not be any פארים [at all, since פארים is not an object that stands on its own] — and in that case it would not say פארי המגבעות .
