To wear a black dress to a wedding?

[lockdownbabyx]

7 months postpartum so I don't really feel comfortable in much at the moment. For some reason I feel more confident in black.

The wedding is end of September and we're going all day. What do you think? Is an all black dress ok?

My sister wore black to our mother's wedding. Mother was marrying another woman, so I'm certain it was a disapproval kinda thing.
In your case, could you wear something that at least has a little bit of colour on it or even a black skirt, coloured top and a black jacket?
