Below is a list of brands/stores in the USA which stock non petite clothing available in a Size 0 or larger which may be suitable for petites. This information has been gathered from visiting the retailers website.
Please note that alterations may be need to ensure a good fit. E.g. Size 6 trousers will probably need shortening unless you opt of a cropped pair which may be a perfect length for your petite legs.
If you notice that any of the links are not working or that I have missed out a store/brand that would be suitable for petites,please use the Contact Page to let me know and I’ll update it.
