It's always pretty cool to discover something new about an established figure, unless it's that your Michelangelo is really just a Raphael whose mask your brother painted...where're his nunchucks, huh?!? For Miami-classic guayaberas from a guy known for other shirts, check out Marce Coral Gables.
Marce's a Colombian dude who learned the art of custom shirting in Europe before moving to Miami to craft bespoke dress shirts, but the secret story's that he handcrafts totally made-to-order guayaberas, which he'll measure you for and cater to your exact specifications on every detail, from pleats, to buttons, to cuffs, presumably giving University of Miami players the option to go without them for once. Most of his shirts're based off the classic four-pocket look, with you collaborating on things like number of alforzas (front stripes formed by crisp-folded pleats; you choose between two and 12), sleeve length (short, rolled cuffs, etc.), mini or large epaulets, buttons (from mother of pearl to wood), cuffs (from sport to the more elegant French), and collars ranging from high to semi-spread, which's also the offense of choice in 7-on-7 football. Once every detail's decided, you'll run through rolls of fine fabrics (available in solids, subtle patterns, and bold or faint stripes, and also all different sorts of weights), ranging from different grades of Irish linens, to English and Egyptian cottons, to blends imported from Italy, Japan, and Switzerland, which generally come in pretty neutral colors.
Marce also carries a full line of pocket squares and cufflinks to bind your Frenches, and he'll deliver your guayabera within 24hrs, which is how long you gave your brother to run away from home, before you tore him to Splinters.
