I purchased this FINIS for my 10yo daughter who is 4''8 and 90 lbs. She typically wears a size 26-28 practice suit but we sized down to a 22 for a perfect fit. My daughter has tried on several different brands, sizes and cuts of tech suits and she finds this FINIS to be the most comfortable. It is also less of a struggle to get on/off than other suits we have tried. After a few times we got it down to less than 10 minutes!! Due to her young age, she has found some of the more advanced suits with compression panels to be very uncomfortable, therefore I would recommend this suit for a younger swimmer. She has worn it for 3 days of time trials and a 4-day Championship meet with good results in terms of dropping time. I am not sure how long the "magic" will last but have not observed any wearing yet. We have ordered our second suit (same size and color) for her next Championship meet just to be safe......stick with what works!
