Boulevardier's Hat ★★

Taken all the way down to base materials, one Boulevardier's Hat is 3 crafting steps deep and needs 2 intermediates — True Linen ×1 and Twinthread ×2 — which resolve to 5 distinct raw materials totalling 17 units, plus 12 crystals.

That bill outweighs 7,161 of the 13,602 recipes tracked here and 916 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 8 are burned by the intermediates, so the real crystal cost is 4 Lightning Cluster, 4 Lightning Crystal and 4 Wind Cluster.

Every step is Weaver work, from a Lv 68 intermediate up to the Lv 70 finish, so one class covers the whole chain.

3 of the 5 raw materials come out of the ground, and one of them is time-gated: Hingan Flax (2:00, 14:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Twinthread has the widest use: 109 recipes call for it, spanning six of the eight crafting classes.
