"I purchased this suit for my 10-year-old daughter, and she absolutely loves it! It seems to be of decent quality and has vibrant colors. However, the sizing is definitely not true to size. I ended up getting a size 12 for her, which fits well but was a bit loose when wet. Straps aren't adjustable, so keep that in mind!"

"This suit fit my daughter perfectly; she's slim and 5'2". The material is nice, and it's nicely lined. The cute straps and tasteful side cutouts make it look great without being overly revealing. I had a good experience, but I noticed others mentioned that the sizing can be tricky."
