Yeah I’m not sure I agree with that at all . The fact she’s being advised of frumpy options is quite common on this board, frumpy is recommended regularly. Christ the amount of Joanie dresses I see recommended is mind boggling. Thays not the dress code, it’s the people recommending dresses, possibly due to their own age or sense of style.
it’s also not they don’t want people to look glam, they do. It’s just nothing revealing, in a kind of keep it classy vein. It’s really not that deep. It’s a military black tie event, as said, I’ve been to them, and it is not no one can be glam and no one can be sexy and everyone has to be frumpy. It’s a simple dress code, which really translates as nothing strapless or short.
No one needs to be all defensive, some short and strapless outfits can be tacky, let’s not pretend otherwise. Sure some aren’t, but there is no doubt some can and they aren’t looking for women to turn up looking like love island rejects.
