Who stands closest to the bride?

I have only heard this discussed once and the position taken was that the maid stands closest so that she can tend to the bride's needs. She is single and has no other responsibilities at the wedding (presumably referring to spouse and children).

I would say matron than maid

Traditionally yes. Eta oh I guess I misunderstood the question. If you have 2 maid/matrons of honor then its just up to you who stands next to you.

Same dilemma I'm having, I was told the matron stands next to the bride

Matron then maid is what's most traditional

Traditionally matron I believe. My sister is my maid and my bf is my matron. I'm having my sis stand next to me though!

I had both and they decided amongst themselves. My matron of honor is incredibly not religious (catholic non mass ceremony) and I think was more comfortable sitting in the pew.
