May, 1819, La Belle Assemblee:

At length the spring and near approaching of summer have asserted their rights, and all the paraphernalia of winter has been thrown aside; or, according to its value and the economy of the wearer, has been carefully deposited in the cedar chest, to be renovated and new modelled as soon as the chilly season shall wave her icy sceptre over Fashion’s changeful dominions. [...]

Many extant garments show evidence of having been remodelled to accommodate the changing whims of fashions: front-closing gowns have been altered to back-opening gowns, waistlines are raised and lowered, flounces are added and removed, sleeves shorted or undersleeves added, necklines re-cut, &c.
