I am wearing it to my mom's afternoon wedding. It's going to be low key with a handful of people at a winery. It should be fairly warm out and I'm not sure what to wear with it. I have some yellow Chloe t strap flats but I think I would like to dress it up a bit more at least for the ceremony.
Would love some ideas
