See-though（シースルー） という言葉は日本でも結構浸透していますが、「透けて見える」という意味です。同僚の方は インナーをあえて見せる“A see-though dress”を着られていたんですね！
Transparent and see through both mean that something allows light to pass through so what is behind can be clearly seen
E.g. Your clothes are transparent. I can see what you are wearing underneath
The sea is so transparent I can clearly see the fish
That shirt is see through
The curtains at the window are see through. Everyone can see into the house even when the curtains are closed
Transparent やsee throughとは、どちらも光を通しているという意味で、その後ろがクリアに見えるときに使います。
E.g. Your clothes are transparent. I can see what you are wearing underneath
君の服透けているよ。何を下に着ているかわかる！
The sea is so transparent I can clearly see the fish
海がすごく透き通っていて、さかながよく見える。
That shirt is see through あのシャツは透けている。
The curtains at the window are see through. Everyone can see into the house even when the curtains are closed
あの窓のカーテンは透けている。だからカーテンが閉まっていてもみんな家の中が見られるんだ。
If something is 'see-through' it means the material is transparent, or partially transparent.
"My god, I can see your bra clearly through that blouse!"
"Oh, does it look bad?"
"Maybe just a little too revealing."
"Oh dear!"
You may also comment on the colour of your friend's underwear. That way he'll know his clothes are see-through.
"Nice green underwear you're wearing today!"
"Is it that see through?"
"Yes!"
'see-through' とは、物質が空けているまたは部分的に透けていることを意味します。
"My god, I can see your bra clearly through that blouse!" ブラウスからブラが透けて見えるぞ！
"Oh, does it look bad?" ええ、だめかな？
"Maybe just a little too revealing." ちょっと見えすぎかな。
"Oh dear!" まじ！

Are you aware that your underwear is showing through that outfit?
1. I can see your undergarments.
The word "undergarments" is another word for underwear.
2."I can see your underwear."
This is a basic and direct statement, to let the person know that you can see their underwear.
3. "Are you aware that your underwear is showing through that outfit?"
This is a polite approach, by asking if the person is aware if their underwear is showing, you are assuming that they might not be aware.
1.I can see your undergarments.
（下着がみえています）。
*Undergarmentsはunderware(下着)の別の単語です。
2.I can see your underwear.
（下着が見えています。）
*これは、下着を見えていることをその人に知らせるための基本的で直接的な言い方です。
3."Are you aware that your underwear is showing through that outfit?"
（あなたの下着が洋服から透けて見えているって知っていますか）

I just want to let you know that I can see your underwear through your shirt.
The first two sentences have openers used when whispering or showing discretion towards someone. When somebody's undergarments are showing in public, it is often considered an embarrassing happenstance. It is important to use a low voice or hushed tone when speaking to someone about their underwear; "psst" and "ahem" are more secretive terms in getting someone's attention. The third sentence is the least assuming. By indicating, "I just want to let you know" or "I thought I would let you know," you are not making assumptions about that person's appearance. Certain fashion trends may make showing one's underwear an intentional statement where that person fully knows how they are presenting themselves.
はじめの2つの文は、相手にささやいたり、配慮を示しすときに使われる出だしです。
誰かの下着が見えているとき、恥ずかしい偶然の出来事と考えられます。誰かに下着のことを話すときは、小さく静かな声のトーンで話すことが大事です。
"psst" （あのね、ちょっと）や "ahem" （人の注意を引くときの言葉）は、誰かの注意を引くより内密な言葉です。
3つ目は一番思い込みではない表現です。 "I just want to let you know"（ちょっと伝えたいんだけど）や"I thought I would let you know,"（言っておこうと思ったんだけど）ということで、相手の身なりに憶測を立てているのではないことを伝えます。
あるファッショントレンドは、わざと下着を見せることもあるかもしれないので、そういう場合は自分がどう見えているのか本人はわかっているのです。
