Very Insecure Need Help

So I met this guy like four months ago on bumble and we talk everyday but haven’t met in person yet. However, this Friday he wants to go to a concert and I’m just feeling really insecure about my body and if he’ll think I’m ugly or not. I’m not sure what to wear to fit my body type so if I could get some help. I really don’t wanna look like a fat pig when I meet him )-:

This is what my body looks like rn sorry pretty blurry. I have trouble finding clothing that’ll accentuate the right places. What do y’all think?
