Teresa from Dandelion Drift shows how to make a rash guard swim top with a built in shelf bra. With the shelf bra, she can wear the rash guard without having to layer another swim top underneath. She started with the new Union St. Tee pattern by Hey June, but this will work with any basic t-shirt pattern. Go to Dandelion Drift for the tutorial.
