The sentence in the image has several grammatical errors. Here is a corrected version:
"Just because I'm wearing revealing clothes doesn't mean I want to be disrespected. Allow me to be confident with my body and to wear what I like, and lastly, stop assuming that ladies dress up to impress boys."
Explanation of Corrections
* "Not because..." to "Just because...": The phrase "Just because" is a more natural and grammatically correct way to start this kind of sentence in English. It sets up a causal relationship (cause and effect) more effectively than "Not because". The original phrasing is a common mistake and doesn't clearly convey the intended meaning, which is to say that the one action (wearing revealing clothes) does not automatically lead to the other (wanting to be disrespected).
* Punctuation: The original sentence lacks proper punctuation. A period should be used to separate the first two independent clauses. The comma after "like" is a good addition to connect the final thought. Additionally, a comma after "lastly" helps to set off the transitional word, making the sentence flow more smoothly.
* "impress boys": The correct preposition to use here is "to", not "for. You "dress up to impress" someone. The word "for" would be used in a different context, such as, "This gift is for you."
