Hi momsh! Try checking Carousell or Facebook Marketplace, a lot of us moms doon nag-sesell ng preloved clothes, and XL selections are usually okay dun, especially if you're patient with scrolling. You can also join some local buy-and-sell groups sa FB, sometimes may mga listings din ng bulk preloved clothing na sulit, tapos pwede ka ring mag-post kung ano specifically ang hinahanap mo para ma-reach out sayo ng may available.
