Definitely a size small

Perfect fir

It fits me pretty well and I like how vibrant and energetic the color is!

I love the color but the fit is a bit too small. I am not a large girl by American standards at all but I wanted a good coverage bikini. I ordered a large size but apparently I should have ordered an XL. Both the top & bottoms were a bit too small. After waiting a few weeks to get this item shipped to me, I am disappointed in the way it fits. I also ordered another one in a different color which has not yet arrived. I am sure it will be exactly the same situation. I try to order bigger than I would normally but I never seem to get the size just right whenever it comes from Amazon sellers not in the USA.
