My sister just texted me that she was looking online for shoes to wear for the wedding and she sends me a photo of them. I had asked all of my bridesmaids to wear silver shoes so she thought because they are silver that I would be okay with them. My wedding is formal so I don't really think Keds are appropriate. I am not buying her shoes so do you think it is out of line for me to tell her I don't want her in sneakers for the wedding? I want her to be comfortable, but there a ton of different more appropriate options she could have selected like flats or sandals. I have linked the shoes below as well as the dress she plans on buying.
