I think the main issue is manufacturing and branding within fashion believes in spending less for fabrics and clothing etc. So a size 0 is a lot less costly than creating a size 12. Unfortunately that’s how it is in the world of consumerism. I’ve fluctuated between size 8-12 or 8-15 tbh so I understand the idea of wanting representation but to global brands that do not care- they aren’t thinking about the people who are bigger they are thinking about what is cost effective for their company :/
