Looking for this specific 'lady finds her prince charming' kinda hostorical themed comic!

I know it was a webtoon, with a medieval/historical setting (princesses, ladies and all that jazz) and the main character once entered an even dressed in a simple, dress that's more akin to a cocktail dress than those obnoxious, puffy ballroom dresses from olden times.
People I believe described/made fun of her because it was so little fabric and slender to her body that they called it underwear/a night gown.
That's the only scene I remember.

I THINK the MC was a young lady with red hair and the dress was green with golden details. But I am not entirely sure.


Does anyone know this?
