Quick answer
Choose the Sunshine Set if you have a smaller chest (A-B cup) and want a lightweight cotton set for lounging or light activity. Choose the On a Vacay Set if you have a C+ cup or prefer more coverage and a roomier fit for relaxed days.
Chest coverage and fit differences
The Sunshine Set is designed specifically for smaller chests, with less coverage in the top. If you are a C+ cup, the brand recommends the On a Vacay Set for better support and more coverage. The On a Vacay Set also has a more forgiving fit, with a tip to size up if you are between sizes.
Material and intended use
Both sets are made from 100% cotton, making them breathable for warm weather. The Sunshine Set is marketed as a warm-weather companion that pairs with every plan, while the On a Vacay Set is described as a throw-on-and-go option perfect for rest days. Neither is designed for high-impact workouts, but both work for lounging, errands, or light movement.
