Is this how sponsorships work?

Hi all, I don't normally create threads here but I am quite puzzled at the moment. Sorry if this is wrong thread. No offence intended :D

Here's the thing, due to my dancing and DJing efforts, social media presense, etc … I was noticed by this clothing brand. I will not out their name, they seem like OK people.

What they want from me is use their cothes – shirts, hoodies, etc … post pictures of me wearing their clothes while I am doing my usual stuff … pretty much standard…
