Husband Worried About Wife's Revealing Saree Attire Worn By Father & Uncle

It's been 6 years of my marriage, but my wife still don't know how to wear saree properly. Generally she wears salwar suit, but there are some occasions where it becomes important for her to wear saree. She wears saree twice in a week minimum. Earlier, my mother was helping her, but after 2 years of my marriage, my mother died. As of now, me, my wife, my 2 years old son, my father & Jagdish uncle (servant who is with us from more than 20 years) staying in our home. I help her many times to make her wear saree properly, but the timing when she needs to wear it is the timing when I am mostly busy. So, nowadays from 4 years my father & Jagdish uncle help her to make her wear saree properly. I suggested her to take help from youtube or get help from any female neighbour, but she said she is still not able to understand from youtube. Neither those female neighbours will come regularly for this. The problem is that there is too much of her body exposure when my father & Jagdish uncle make her wear saree. She reveals too much of her body parts while wearing saree. Any husband can feel uncomfortable if any other man will see his wife in such condition. I asked her to do it in decent way, but she said there is no other option. What should I do ??
