I bought this suit and another in a similar style and both fit perfectly. I am 5"2', 119 pounds and got the size 6. As is the other Bleu Rod suit, this one is very well made. It's lined, has reinforced seams, etc. It's hard to find clothes this well made anymore. The pattern is so CUTE! I really love it. It's perfect for vacation. The bottom coverage is just right - not too much but also not the "thong" look that's so in today. I bought this to legit swim in the sea on vacation and it looks like it will go the distance. Highly recommend this suit.
