fmil plans on wearing an off-white dress to my wedding 🤦🏻‍♀️

I texted my FMIL about a week ago saying I wanted to take her dress shopping for her mother-of-the-groom dress. I had taken my mom dress shopping the week prior. It was agreed beforehand, mother of the bride & groom were to wear navy. She says she doesn’t want us buying her dress, she feels bad she can’t help with paying for anything in the first place, which I understand so I didn’t pressure her. She says she wants to get a dress when she gets paid next month. I said ok, wedding isn’t until October 7th. She texts me last night a pic of a dress she found online... and it’s literally white! Like eggshell/off white but definitely white!! I’m literally staring at my phone not knowing what to say.... so I’m like does it come in navy? And she’s like yes but I like the white better. I didn’t even respond! FH comes home from work the next day and is like “did you see what my mom wants to wear?” I’m like yeah!!!! She’s your mom you better take care of that!!

I know he wont say anything. So I’m hoping by the time she gets paid that she will want to go shopping with me. I’m trying not to sound crazy lol but really?! Also she says she is on a budget, and this dress was $85. We got my moms at Ross for $14.99 and it’s gorgeous 🤣

let her wear white?? Am I overreacting?? 🤣
