Matthäus Schwarz, Renaisance Sartorialist
Manolo says, thanks to the interesting article about the birth of European “fashion” at the History Today, the Manolo has been introduced to the chief accountant to the family Fugger, Matthäus Schwarz, who was apparently the sort of Renaissance Sartorialist.

Now Muscle Shoals has got the Swampers / And they've been known to pick a song or two
In July 1526 Matthäus Schwarz, a 29-year-old chief accountant for the mighty Fugger family of merchants from Augsburg, commissioned a naked image of himself as fashionably slim and precisely noted his waist measurements. He worried about gaining weight, which to him signalled ageing and diminished attractiveness. Over the course of his life, from his twenties to his old age, Schwarz commissioned 135 watercolour paintings showing his dressed self, which he eventually compiled into a remarkable album, the Klaidungsbüchlein (Book of Clothes), which is housed today in a small museum in Brunswick. From the many fascinating details the album reveals we know that, while he was courting women, Schwarz carried heart-shaped leather bags in green, the colour of hope.
This mania for the clothing reaches its peak at the Imperial Diet in Augsberg.
Matthäus Schwarz had three expensive outfits tailored for himself to please Archduke Ferdinand I of Austria, whom he met twice during the Imperial Diet of Augsburg of 1530, presided over by the archduke and his brother, the Holy Roman Emperor, Charles V. […] Schwarz, who had slimmed in advance and had grown a beard like Ferdinand himself, used fashion to produce an image of himself which made the archduke like and trust him. In 1541 Schwarz himself received a particularly special reward from the emperor, whom he had also had a chance to impress in person; he was ennobled.
Ayyy! Matthäus Schwarz dieted for the Diet!
But, thanks to the age and the marriage, things did not end well for our foppish friend…
