details in the fabric

"..they (wife) are as a garment for you, and you are as a garment for them..."
Al Quran, Al Baqarah 2:187

I find the meaning, encompasses the total idea of being a spouse.

A garment protects the body from discomfort/danger (heat/cold).
It covers up the person, shielding the shameful parts and aurats from others. - I think this part is important, a spouse should shield their partner's weaknesses from others. It is contained within the family.
It beautifies the person. - Spouses should reflect or show the good sides of their partners.
It reflects on the person. - The reaction of a partner in front of others, may be able to reflect on what kind of a person the spouse is.
It makes them complete.

And, garments differ, depending on the details in the fabric. But one thing for sure, the details in the fabric will show that all garments are not perfect. However, we learn to live with the defects - either my mending them or by accepting them as they are - after all, it's the details in the fabric that differentiates one from the other.

Coincidentally I also came to know, from the 'eat, pray, love' book that the root word for the Italian word for 'friend', is garment. - which carries similar idea. But it suits a spouse even better.
