I LOVE the linen dress and the way it’s styled in the photo. The two other dresses look great too. The mother of the bride dress has a nice flirty vibe.
I totally get why you’re doubting your choice. I would be doing the same given the response from the bride to be. It’s nice of her to let you know what others are wearing so that you have the opportunity to reconsider your outfit if you want to.
I looked at your profile to get a sense of what you like. I noticed you like Eileen Fisher. You mentioned Diane Keaton. A great example of someone who had her own style. The linen dress does have that vibe. The other two dresses, while also nice, are a different look and don’t seem to align with what I read in your profile.
Did you have the opportunity to try the linen dress on yet? How do you feel in it? It seems your dress will be different from the others. It would be great if you could still wear it with confidence and not be wondering if you’re dressed appropriately at the wedding. Trust yourself. If you continue to not be sure about your selection, it might be worth looking at something else that you feel great in. I hope for you that you’ll be able to stick with the vibe you enjoy. And importantly, I hope you have an enjoyable time at the wedding.
