There is a Formosa on sale that has my eye (Minnis houndstooth). All of my suits are bespoke save for a couple of older RLBLs. I previously tried a Formosa tux and had minor fit issues with the lapels bowing. I suspect the flannel wears a little easier, helps hide the minor fit issues, plus is available in a L (the tux was an R and I am definitely an L). For those of you with Formosa RTW experience, should I take the plunge?
