Athena Clothing question

My first tri is in about 6 weeks, and I'm starting to get obsessed with everything, but mostly now I'm trying to find a good tri top and shorts to feel comfortable in on race day.

The issue: The majority of my weight (that makes it difficult to buy clothes) is concentrated in my chest region, so with normal clothes I often find that if something fits there, it's loose on the rest of my torso, or it fits my torso but doesn't even come close to covering my chest. With all of the athletic gear I've bought, it's sorta stretchy, so the problem translates to tops being too short. Does anyone have a suggestion on tops or shorts? Or a single piece if that would be better?

Any advice helps! Thanks!
