Top and bottom set. The white floral part of the top is slightly yellowed, but it's only noticeable up close. See photo 4. The bottoms have built-in shorts, so you don't need to wear undershorts, which is convenient. Made in a foreign country, it says 4T, so it's probably around a 100-110 size in Japan. Will be shipped compressed. *This item has been handled by someone else. There may be oversight of scratches or stains.
