I believe I read it was considered makruh tahriman to wear clothes in an odd manner in salah.
Personally, I did what I did to cover my awrah of my arms. But because of how strangely it was worn, it was difficult for me to properly put my hands under my chest and touching my chest because the clothing was bunched up. And when standing up from ruku, my hands weren’t sitting straight upon my legs and were lifted.
Thus, it made salah a little difficult for me. Now I wonder, because this is a problem I afflicted on myself and also because I was aware of the ruling of makruh tahriman prior, would my salah be void?
I’d hope in other madhabs they’d give dispensations on this matter.
Wa’alaykum as Salam wa rahmatullahi wa barakatuhu,
Since your ‘Awrah was covered fully, your Salah will be valid.
In the future, try to dress in such a way that you can accomplish all the Sunan and Mustahabaat (preferable acts) of Salah, and in a way that your dressing does not affect your concentration.
And Allaah Ta’aala knows best
