Beautiful Tafseer!
هن لباس لكم وأنتم لباس لهن
They (spouse) are a garment for you and you are a garment for them.
Commentary: Allaah used the following words to describe marriage as the same as wearing ones clothes to protect one from the cold and heat; similarly marriage is a means of safeguarding oneself from sins.
Also marriage provides peace and tranquillity to the heart and there is a physical bond between the husband and wife the same way ones clothes are closely attached to a person.
