Bubble shorts can be practical for young toddlers because the fuller shape leaves more room through the seat than a close-fitting short. An elastic waistband also makes the shorts easier to pull up and down during diaper changes or potty training. This set uses relaxed bubble shorts with an elastic waist, but it is not specifically described as diaper-adapted clothing, so the final fit will still depend on the child's diaper, body shape, and size selected.

A sleeveless top should sit comfortably around the underarm without digging into the skin or leaving a large gap that exposes too much of the side of the body. Your child should be able to raise both arms and reach forward without the armholes pulling or rubbing. This top has a sleeveless design with a gathered neckline, so check the underarm fit as well as the chest when choosing a size.

If your child is between two sizes, check height and weight rather than choosing from age alone. For this set, the fit is listed as true to size, and sizing up is specifically recommended when a child falls between sizes or when you want a roomier fit and a little more growing room. Because a two-piece outfit has to work through both the top and shorts, also make sure the larger size will not leave the elastic waist too loose.

Use a gentle wash routine and avoid aggressive rubbing directly on the flower appliqués. For this set, machine wash cold with similar colors, do not bleach, and hang dry when possible. If ironing is needed, use low heat and avoid pressing directly onto the decorative flower details.
