Should I or Not?

I am very self-conscious, especially when it comes to swim wear and intimates. I was invited to a friends graduation/birthday celebration & it’s a pool party. I have to get a new swim suit because I don’t have one that does what I need. & I’m obsessed with Torrid - they have such beautiful things for plus size girls. & so, they have this swim suit that I really l like, but I’m not sure. I’m hoping to be able to the store & try it or one similar. I am the girl in the blue dress with the white sweater.... But I’m not sure... Should I go for it or not??
