  • SO cute!!!
Size: Small Color: Owl
I bought the owl onesie for our Halloween celebration day at school (I’m an elementary teacher). It’s such a cute costume and fit just right! Definitely very soft and warm, which I appreciated since I tend to feel cold. If you tend to get hot easily just beware it’s a very warm onesie! It arrived in a vacuum-sealed bag, so was VERY wrinkly when I pulled it out of the bag, but after running it through the washer and dryer it was perfectly fine with no wrinkles or issues. ... show more

  • Cozy
Size: Medium Color: Chipmunk
I got thie chipmunk one for halloween. Its very warm and cozy. It is durable. I like the pockets. I am 5'4 and got a medium. The height of it was perfect. It has plenty of room if you have a few extra pounds. The hood is a little big, but not annoyingly so.

  • Needs pockets
Size: Medium Color: Walrus
The Adult Onesie Halloween Costume in the Walrus design is a fun and creative costume choice that garnered plenty of attention and laughs at the Halloween party. This cozy and comfortable onesie offered a unique and whimsical look that stood out among the usual Halloween costumes. The design of the Walrus onesie is adorable, with attention to detail and a cute walrus face on the hood. The soft and plush material made it cozy to wear throughout the evening, even on a chilly Halloween night. The onesie's one-size-fits-most design is versatile and accommodated various body types comfortably. The loose and baggy fit allowed for easy movement, making it convenient for dancing and socializing at the party. Putting on and taking off the costume was a breeze, thanks to the front zipper closure. One minor drawback was that the costume lacked pockets, which would have been helpful for carrying small essentials like a phone or keys. ... show more

  • Comfy, cute, and a great price!
Size: Large Color: Cow
I ordered the cow onesie (Size Large) for my girlfriend. I'm definitely impressed! The fleece is very soft to the touch and easy to sleep in. It keeps you nice and warm without the trouble of having to drag it everywhere with you around the house like a blanket - it moves with you! It's also breathable enough to allow you to wear it in the summer. (Which is an extra plus!) The onesie is baggy, but gives you a very lean look! Some of the onesies I've seen in person and online have the leg openings too long, which causes you to have the "beer belly" look and that's certainly not something you want to have in a cow onesie!! Luckily, this onesie's legs are just right! The onesie has a set of white plastic buttons running down the center to close it. I've seen some reviewers complain that these don't close all the way and can sometimes show your clothes underneath, but I (nor my girlfriend) didn't have this problem at all. It keeps everything contained! My only critique is that the stitching is a bit sloppy (I had to spend a couple of minutes snipping off the extra strings after I took it out of the packaging) but for the price, it's to be expected. I also had a horn damaged when it was put in the bag, so it doesn't stand up on the hood like the other one, but again, that's simply just me being a bit picky. Overall, this onesie is definitely worth it! I will definitely be buying from Silver Lilly again! P.S. ORDER THE SIZE BASED ON THE MEASUREMENTS IN THE DESCRIPTION NOT THE SIZE CHART NEXT TO THE SIZE OPTION. I cannot stress this enough! The onesie fits perfectly. It's based on your height. So if you're tall or just want a really baggy onesie, order the largest size possible. If not, order it based on your exact height. Do NOT size up. ... show more

  • So big and comfortable
Size: XX-Large Color: Giraffe
Got this for a pajama party. It was a great success and so comfortable. It is loose fitted extra space. Love it and would recommend for any adult party.

  • Button Closure
Size: Large Color: Duck
Everything was as expected except for the fact it has a button closure. I chose this one because the duck in the picture is clearly wearing a zipper. My friend I got it for has some dexterity issues. Sadly this duckie will never get the chance to fly. But soft. True to color.

  • Extremely Comfy and Warm!
Size: X-Small Color: Cow
My 10 year-old wore this costume for Halloween. Although it was a little big (which I expected), it was not an issue when wearing it. She was warm and cozy all day. It was the first time she didn't want to taker her Halloween costume off. Also, I have washed it multiple times and it still looks great! I would definitely recommend this onesie. ... show more
