Reference for Shabbat 93:3
(דניאל ד, טז) אישתומם כשעה חדא ואמר הכא נמי דאית בה קרטין אמר אביי קרטין בי רבי מי חשיבי
And should you answer, They were fit for the poor, — surely it was taught: 'The garments of the poor for the poor, and the garments of the wealthy for the wealthy'.<span class="x" onmousemove="('comment',' The reference is to the minimum size of material which is liable to defilement as a 'garment'. The smallest size which has any value to a wealthy person is three handbreadths square; if it is less, he throws it away. A poor man, however, endeavours to find a use for it even if it is only three fingerbreadths square, and that accordingly is his minimum (cf. supra 26b seq.). These are the minima for the wealthy and the poor respectively which are technically called garments.

The same principle applies here.
