The girl is a ditz. It is perfectly possible to cover up cleavage if one is well endowed.
She’s not well endowed, she’s fat.
Looks like a blivet.
You’re dead wrong. I saw this girl on t.v. and she is no ditz. It showed her dress and you could tell that the poor girl has enormous breasts but the dress itself was not at all low cut. Some idiot educrat screwed up badly and ruined this poor girls prom.
Betting she likes the attention.
