my mother-in-law bought a dress almost identical to my wedding dress.
she was searching for a dress for months and continuously lamenting about how MY mother purchased the ONE color she intended to wear. this, despite having told me to let my mother pick first and then tell her so she would wear a different color. after months and months of, quote, ONLY finding dresses she liked in either blue or white (red flag #1) she purchased a pale (very pale pink and grey) floral, floor length gown. the only problem being, it was strapless, trumpet shaped, floor length and made of delicate, individual silk ribbons. it was literally, identical to my wedding dress in almost every way except for the color (my dress which she had seen and said she cried because of how beautiful it would look on me).
i freaked out and had to actually tell her i thought they might photograph too similarly and would make for odd photos. she returned it, but then continued to talk about how THEY WEREN'T THAT SIMILAR to anyone who would listen AT the actual wedding festivities.
