bicep curls!! what the, I'd be doing lots just so Id have the strenght to strangle her

Do what the others have suggested and outline your concerns to her face to face. If she is any kind of friend she will try and come to a compromise with you. If not just say you are hoping to still bf matisse and it might be tricky to care for her and be in the bridal party if you dont want a scene but want to opt out.

I have picked a dress for my bridesmaids but have told them to tell me if they don't like it want straps or different lengths etc. (they all said they like it and 2 of them are the type that would just say it if the hated it)The design isn't one I absolutely love but I think it is the best design for girls with very different shapes. I have 4 girls in the bridal party and think it might have gotten tricky for them to pick one and agree on it.
