So, I have 2 BMs and I have choosen dresses for them that are super cute, flattering and inexpensive ($50) that they can wear again to other events. My problem is that I have mentioned to them several times that we need to order their dresses (which they will be paying for) but they keep dodging it and putting it off. Now the wedding is less than 4 months away. How can I tackfully bring it up again without sounding like I am badgering or being demanding?
