I am under the impression that only the Lady In Waiting is the only "maid" who is aware that MC is a boy. So the other maids could have noticed the boobs and assume that every thing is normal, and the lady-in-waiting would assume that he padded while fixing his underwear.
Can we just address the plot hole of the prince asking why she doesn’t like jewelry? Supposedly, she’s a dude. Why would a ‘lazy knight guy want jewelry? And he has no problem calling her Estella naturally and basically being cheesy and romantic. 60% sure he knows she’s a girl. Also, how do the maids hat help her dress not notice that she has boobs? She comes out in underwear...but I guess the underwear itself has padding to make it look like she has the boobs...hmmm
