'well-fitted' originates from the combination of 'well,' meaning 'in a good or satisfactory way,' and 'fitted,' the past participle of 'fit,' meaning 'to be the right size or shape.'

'well-fitted' evolved from the Old English word 'fitten,' which meant 'to be suitable or appropriate,' and the adverb 'well,' which has been used since Old English to denote quality or manner.

Initially, 'fit' meant 'to be suitable or appropriate,' and over time, 'well-fitted' evolved to specifically describe clothing or items that are properly adjusted to size.
