Flowers

I had my own bouquet and then smaller bouquets for my bridesmaids. Those were our only flowers!

Usually people have bouquets, boutonnières and corsages for the wedding party and immediate family.
But like pp said I think you could just do bouquets only for the bridal party

We are only going to have my bouquet, and three boutonnières for FH, his best man, and our son who is the ring bearer. My MOHs are going to carry lanterns that I’ll decorate myself. Adding immediate family just adds up so fast and my flower budget was under $350.

I would say to just get whatever you want and is in your budget. I have been to a wedding that had zero flowers and it was absolutely beautiful!

I agree with PP. get whatever you want for your day. If you have bridesmaids they could always carry a single flower to cut costs.

It's totally up to you. The minimum I would do would be a small bouquet for the bride, boutoniere for the groom, and small centerpieces* on the tables. Ideally I would also give flowers in some form to any bridal party members and parents. If you're concerned about cost, these could be mostly greenery and/or filler flowers.
*the centerpieces don't necessarily have to be floral.

Bridal bouquet is probably bare minimum, and that’s all we are doing

The minimum would be zero! My friend is having a 150 person wedding with no flowers (due to allergies). You can do whatever you want!
We’re having a bunch of flowers for decor stuff and having bouquets for the bridesmaids and I. There will be no boutonnières or corsages.
