Using clothing of the kuffar (unbelievers)

The use of clothing of the kuffar (unbelievers) which they have worn
is permissible as long as there is no known najasa (impurity)
regarding it, because the default for things in general is tahaarah
(purity) and it is not overridden by mere doubt. Likewise, what they
have woven and dyed and what has been imported from their
countries are also permissible, as long as they do not comprise
anything haram (forbidden), because the Prophet
(peace be
upon him) and his sahaba (his companions) wore items the kuffar
had woven and made, and likewise the Prophet
(peace be
upon him) wore a Roman jubba (a long outer garment, open in front,
with wide sleeves).
