To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I bought this dress in the 0-3 month range and I haven’t tried it on my 6 week old daughter yet, but I can already tell that it is definitely too large right now for her to wear. It leans more towards being a 3 month size which is perfectly fine since she will need to have something to wear when she is bigger.
