According to Google and Wiktionary both "attire" and "garb" have a plural noun of "attires" and "garbs", respectively. But how could you used either of these pluralised words in a sentence given they already represent a collection of things?
I can't say I've ever seen "attires" or "garbs" used anywhere. I've researched the 1933 Oxford English Dictionary and cannot find any mention of a plural for "attire" or "garb" (unless I'm being blind).
Mike was dressed in his best formal attire. ✔
Michelle wore military garb. ✔
Jack has a large collection of garbs. (?)
Sarah purchased several attires. (?)
The last two just don't seem right? How would you correctly use these words? Are there any significant real life examples?
