Assalamu alaikum Ustadh. If a woman prayed in pants or very loose abaya that revealed her body shape, but only her face& hands were exposed, her body was covered but with such a clothing, so is her Salah valid? (She did so only rarely) JazakAllahu Khairan

Ustadh AbdulAziz al-Haqqan
Valid, but she should wear what is appropriate from now on.
