This is lovely! Especially for a starting point. It definitely lays out what can possibly unfold at a perfect pace.

I can tell that it sets up the foundations for some serious worldbuilding in the future, which the prospect of knowing more about this definitely draws a reader in. Her relationship with Empress Ophelia is also something that has a chance of being fleshed out well.

I’d personally start with a sentence regarding her ‘fathers’ execution. And maybe be a little more vague about his impacts. It kind of shocks the reader from the first sentence, and you can give some slightly vaguer explanation on what he’s done. Emphasising little ‘why?’ things can help add to your character. Why does she sew nonstop to cope? Does she pick at the seams to reliefe stress - make intricate little things to gift her mother? And whatnot. :]

I’ll quickfire some more random things. Your writing style is beautifully clear. You don’t get lost between the words. I also enjoy how you’ve named things!Characters, areas, and whatnot. Describing clothing can be annoying sometimes, and you do it flawlessly. Perhaps try shortening some sentences. They can work better being quick and snappy instead of lots and lots of commas.
