"Cloths" is not the word you need. Try again. Also, "this many" is incorrect. One of the words is right but the other one isn't. "That" before "I have bought" is wrong. Can you work out what the errors are?
No. You haven't bought dresses, I don't think. Mostly, women wear dresses. The word "cloths" was almost correct. You need to add one letter.
"So many" is not right.
"Like I have bought" is not right.
Here is a clue. To replace "so" and "many" you need to use the same word twice.
You replaced "that" with "as". That is correct. I also told you that you needed the same word to replace "so" before "many".
I have never bought ___ many clothes in my entire life ___ I bought today.
The same word goes in both spaces.
