The top piece runs small so it’s good if you have a smaller chest, i on the other hand have a size double D so I will definitely need a white bikini underneath which was the plan regardless. I’ve gained a lot of weight I used to be a small so I’m adjusting to having to get larger sizes I definitely should’ve went with a large but I ordered a medium now I’m wishing I sized up because the top is fitted more like a micro bikini top than it looks with very little coverage. Also the yellow and blue are a lot know predominate than the picture shows. I was looking for more of a light pink with light colours around it but the other colours are definitely darker and stand out more than advertised. I was very excited for this piece it still will get good use but it was a bit of a let down, not true to colour and if you have a larger chest definitely size up… for reference I am 5’3 175lb with a larger bottom half and larger breasts. Hope this helps
