Konfidence Floatsuit, Navy Breton, 2-3 Years

My daughter is a slender 26 pounds 36 inches tall. Will a 1-2 size be big enough for her body? Or should I buy the next size up?

What is the child weight recommendation for suits referencing age 1-2?

Is there a removable bikini bottom on swimsuit for little girls?

Is it usa coastal navy certified?
