I fully support you. I had a hard time convincing my father not to spend too much on my wedding back in 1994. I asked him to keep the number of guests minimum, no band baja, no mehndi (it is totally useless drama). My father got very annoyed over this with me, but I still insisted. My cousins and friend appreciated this bold step to have wedding with simplicity, but when it came to my younger brother's and sisters wedding all those tel, mehndi, dhol, dhamak and entire family and same number of friends were invited, large functions.
It is so difficult to resist the society where show off has become a norm. People want to impress others with lesser money or wealth.
I have seen many rich people having simple weddings, no show shaw.
We should not forget what our religion tells us. We have imbibed so many things from in our wedding ceremonies from Hindu culture and now these have become pathar par lakeer.
The more you become simpler, the more you are close to yourself and at peace with life. The more pomp and show and the less sakoon you have in life
