Should i still have a wedding shower?

I would base my decision off of personal circumstances. Bridal parties are basically a get together that involves gift giving of items that would typically be on your wedding registry. It would be things like necessary kitchen and household items. If you and your FH are in need of those items because you are/ will be moving in together and need them to get your life going, then yes I would say go ahead & have the party. If you are not in need of these items at all or right away then I would consider skipping it.

My FH & I both already had our own homes and when we got engaged we moved in together. My family also kindly offered to throw me a Bridal Shower but since we don't NEED new household items, I am choosing to politely forgo.

You could do a brunch or lunch at a restaurant instead. Skip the gifts, shower games, etc, and just have a nice, small celebration with the people they want to include. Cost wise it would probably be similar to hosting a shower for that number of people.
