House Home And Garden

I’m going to a bridal shower where the invite said a Home and Garden theme and said to bring gifts that the couple can use for home renovations.
Any ideas on what to buy?
I have not seen their house so I am unsure of home decor, etc.
They do not have a registry

I’m getting married in late May, in the evening, in the garden of my home. I really like the color and look of following Nicole Miller dress for a bridesmaid dress (I have three bridesmaids, all three are thin and would look good in this dress):

The trouble is that I’m afraid that it might clash with my dress, which is elegant, understated, and has exquisite detailing. (go to the end of the pictures, and my dress is the third from last:
