Bigger cloths for bigger people

Hello I am a young girl standing up for bigger people not just women but men as well...I go to stores like (Walmart, Kmart, Target, ECT ECT ) and many other places that have yes big cloths but not the size some people need most stores go up to at least a size 3X but lots more people need a size 5X or bigger and I have not none of these stores have these sizes and it's right it is a discrimination against bigger guys (and girls) this upsets me and I'd like to see change right away there needs to be something done and I'm here to help it get done
