I have found a solution. My plan wasn't to complain to her at all, and since she's only making the base coat for me, which would take her about two hours to do without dying the fabric (she's really just giving me a coat with a collar and sleeves attached since I don't know how to do that), she's agreed to re-make the coat once I buy some symphony broad cloth :3 After I explained that I needed a more military look, she was like "yep. Definitely don't want that coat anyway." Since the fabric I'm buying is $2 a yard and I have a 50% off coupon, I won't have much trouble getting my mom to take me to buy it.
Plus, I do trust her, just not her vision when looking at an iPhone xD She's not just some person my mom's friends with, she's the head of the theater department at a local college and the head of the costuming department at a local theatre, ad the person who just gave me a sewing machine because she wants me to learn how to sew xD She's totally fine with redoing the base coat, since I'm still getting to learn how to properly sew on trim and patches :3
