Praise be to Allaah.
It is makrooh for both men and women to wear tight clothes.
What is prescribed is for the clothes to be moderate, not tight and showing
the shape of the ‘awrah or very loose, but somewhere in between.
Prayer offered in such clothes is valid, if they cover the
body, but it is makrooh for the believing man or woman to wear such clothes.
The clothes should be somewhere between too tight and too loose. This is
what is appropriate. End quote.
