I followed the size chart and the fit was just right. There’s enough room underneath for an extra layer without making it look oversized.
I was worried the fabric might feel rough, but it’s incredibly soft and plush. My little one looks so cozy in it and can move around comfortably.
Such a fun outfit for colder weather. It’s warm, comfortable and ridiculously cute — we’ve already gotten so many compliments on it.
The plush material feels much nicer than I expected. It’s soft, cozy and looks like an actual outfit rather than a cheap costume.
I was unsure about ordering the size online, but the measurements were really helpful. I chose based on the chart rather than age alone and the fit turned out great.
The hood is adorable and the little horns hold their shape nicely. It gives the whole outfit such a cute monster look without feeling bulky.
My biggest concern was whether my baby would be comfortable wearing it for more than a few minutes. The fit is roomy and doesn’t seem restrictive at all.
Getting it on and off is much easier than I expected. The front zipper makes changing quick, which is a huge plus with a little one.
