I looked through the size chart and ordered 10-12 but my son couldn't fit it under the hips. Swapped for 14-16 and with just an inch more fabric I couldn't get them past my ass. I finally got the 18-20 and they fit around the waist but now he looks like he's wearing capris unless I pull them up to the navel which is fine we don't need any plumbing at the school pool. The baby weighs only 103 pounds, and in terms of breast size, it is almost the average of 10-12 measurements. I think they need to reconsider the size chart and measure hips instead of weight and chest. Suitable for 10-12 in other attire. So definitely small. I recommend,
