Hi Im new here and I just wanted to say that this place seems great !!! I was never really in a wedding where I was old enough to be responsible for help w the planning so I sometimes feel like Im in over my head w all this

Ok so for my colors I was wondering people's opinion ... My dress is Ivory and its outlined in champagne , so I have 2 questions ..
1) Should my bridesmaids dresses be a warm toned color like mine ?
2) Do the groomsmen's vest have to match the color of my girls' dresses?
Im getting married in August of next yr and I like this terracota color ( davids bridal ) and Im thinking thats a lil girlie for the guys ?? So could they just wear champagne colored vests ??
What color schemes do you guys suggest for August weddings ? Usually Im good at this stuff , but Im really stumped w this for some reason lol Thank you , for taking the time to read this !
