Questions parents ask
Answered from 17 Amazon reviews we read and the product listing.
Does this mermaid costume run big?
Reviews are mostly positive on fit. 2 of the 17 reviews we read said it fit well or perfectly on a 3-year-old and another child, but two others found it a little or very big, so compare against the size chart.
What comes with the mermaid costume set?
Reviewers received a top, a tail skirt, a long red wig, a crown and a wand. One noted the tail skirt has detachable beads hanging from the waist.
Is the red wig good quality?
It looks right but quality is mixed. Reviewers liked the bright red, lightweight wig as a great addition, but one said it matted up immediately.
Is this mermaid costume well made?
Most said yes. 3 of the 17 reviews we read praised the quality and durability, though one found a poorly sewn sleeve hem. One reviewer also noted the scales are shimmery fabric, not sequins as described.
Is the top of the mermaid costume adjustable?
Yes, reviewers confirmed adjustable straps. One mother said the top has 3 button holes so she could tailor the fit to her 6-year-old.
