Is this too Bridesmaidy

We are supposed to be attending three weddings this year and I'm wondering if this dress looks too much like a bridesmaid's dress. The first wedding there is no real indication as the recommended attire for this wedding. The ceremony and reception are on an island in Boston, MA. The ceremony will be outside and the reception will be in a partially closed building. I have no idea what their wedding colors are. The second wedding is at a country club. The ceremony will be outside and the wedding will be inside. Their website says the recommended attire is formal, but comfortable. Their wedding colors are purple and either black or gray (not sure which one they ended up picking). The third wedding the ceremony is at a church with a reception to follow at a very modern looking venue. The recommended attire is semi-formal, but says tuxes and gowns are welcome, and so are suits and cocktail dresses. Their wedding colors are slate blue and black. I would probably get the dress in burgundy that way I knew I wouldn't be wearing the same color as the bridesmaids in the second and third wedding. I'm also not sure if it fits the recommended attire for the third wedding. Any opinions?
