Help Me Dress Groomsmen,usher/usherette,ring Bearer!

I’m not an expert. I can only say what we are doing.
MOH/Bridesmaid are all wearing same plum dress
Groomsmen are all wearing a charcoal gray tux w/ black shirt from Men’s Warehouse, a plum vest & FH bought them a purple/gray/black tie that will also count as one of their groomsmen gifts.
Groom is wearing the same w/ a slightly different tie.
junior groomsmen are wearing charcoal gray dress pants, black dress shirt, charcoal vest & plum bow ties & suspenders (bc I’m that person).
FGs are wearing an ivory dress from David’s ($40) that matches my dress enough w/ a little sash that also matches my dress & a flower headband.
RB (he’s a dog) is wearing a custom charcoal suit (once again bc I am that kind of person) with a plum tie.

For the groom's men, I would do a charcoal or that beautiful Cobalt blue suits, groom same but different vest. Chose one of the bridesmaids colors for ties, vests, pocket squares, chose a different one from groom (unless you do the blue suits, then I would do a silver/ grey to match your dress)

Your flower girls look more casual, so for RB, I would go with a matching Polo and navy or grey dress pants, depending on suit color.

Ushers black dresses are fine, I think then men black shirt black pants is a little wait staffy, but I am not sure what I would recommend, maybe Jewel tone shirts.
