Albert Einstein was many things--including a designer of clothing, and a patented one at that. He applied for and was granted a patent in 1936 (not an unbusy period in which he must've been noodling this thought around in his head, that blouse thing along with gravitational lensing, that pesky quantum mechanics, and the EPR paradox and all that) for an expanding waistcoat.
Well. Einstein had his hand in other patents, including a rather famous one regarding a refrigerator with no moving parts (along with the great Leo Szilard, the "Einstein-Szilard electromagnetic pump), as well as part interest in gyroscompasses and a hearing aid, and better yet a "light intensity self-adjusting camera" with an "electric eye". And the "ornamental blouse". I suspect that it was all in fun, except that once the thinking had been done, it was thought to take it to the next logical step.
And just as unexpectedly, Samuel Clemens, Mr. Twain, entered the patent field with two efforts of his own--one being a bra-release mechanism, and the other (and perhaps more appropriately) a design for a scrap book the resultant of which looks quite blank and black.
Here's the image from a bit I wrote earlier in this blog:
