Cloths for a 3 year old boy (Carlby PE9)

I am currently going through a divorce and my wife has taken it on herself to secretly move out whilst I was working away. She has taken all of my son’s nice clothes. Leaving me with old, stained or too small things for him to wear when he’s staying with me. I would be grateful for all clothing types to fit a 3 year old boy, especially vests, trousers & pairs of socks.
