Maggie Sottero Cognac Dress-Need Your Advice!!

Hi! I have recently purchased a Maggie Sottero dress (Angel) and am now in heavy panic mode because I cannot decide on colors for the wedding itself or the BM dresses! The dress is listed as "cognac" and actually looks brown in the Maggie pics, but it has much more pinkish/peachy undertones than you can tell. Does anyone have any advice on complimentary colors???

Helpp!!! :)

I`m linking a pic of both the front and back, but also the actual dress when I tried it on to show you the color difference.
