Here is the translation based on your instructions:
"I didn't wear a chest wrap today."
Li Zhiyan only just noticed that Aunt Ting seemed to never wear a bra.
"Aunt Ting, have you never worn a bra before…?"
"Zhao Liang thinks it's a waste of money. He refuses to buy me one."
"Then I'll go buy you a couple of sets."
"Xiao Yan, don't waste your money. I'll go home and grab my chest wrap."
However, Li Zhiyan had already run far away.
...
When Li Zhiyan returned with two shopping bags, he pulled Aunt Ting into the employee changing room.
"Aunt Ting, I bought you some E-cup bras. I'm not sure if they'll fit. Try them on."
"I'll step out for a moment."
"Xiao Yan, how much did this cost? I'll pay you back later."
"Let's talk about it after you get your paycheck."
As he spoke, Li Zhiyan suddenly gave He Tingting a hug and kissed Aunt Ting lightly on the forehead.
"Aunt Ting, I believe once you wear proper clothes, you'll definitely look amazing."
