My husband and I are going to my friends wedding at the end of June. I almost always wear dresses and was thinking of getting a LBD for the wedding. Iam very much into 50-60s billowy skirt fashion and I found 3 dresses I like. Thing is, I would really love to buy these green heels because I don't have many shoes, and haven't been able to wear heels because of my lupus since I'm always attracted to 6" heels. I realized kitten heels are the aesthetic of my usual style and I found these velvet beauties:
And because they're so vibrant I'd go with a LBD like one of these two:
Or something more like what I usually wear with floral because I heard somewhere wearing all black to a wedding is an insult since you wear black to a funeral.
Which do y'all like best?
