Hi,

To integrate clothing size ranges in Odoo, the recommended approach is to use product variants by defining a "Size" attribute (e.g., S, M, L, XL). Assign these attributes to relevant product templates to auto-generate size variants.

For advanced control (like size charts or body measurements), extend the product.template model with a Boolean field (has_sizes) and link it to a custom product.size.range model. This allows you to store measurements like chest, waist, etc.

Hope it helps
