This outfit fits me well. It is not tight fitting at all. Can wear when it's really hot out because the material doesn't cling to you. I'm 5'10, 185 lbs.

I ordered an XL but when it came the top was a 1X and the shorts were in XL. I kept it anyway because I like the flowy oversized shirt look. When buttoned up and not tucked in it looks like a shirt dress. A large would have fit me so ordering your regular size should work. I'm 5'10, 36DDD and 185 lbs with an athletic build.
