  • 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

  • Love it!!
Size: Medium Color: Chicken
It was alphabet day for homecoming week and need something that started with C and this was perfect!! Super soft and comfy, the chick in the pocket was adorable, I did have to iron it flat cause it was a little crinkled but was super easy to do. Would definitely recommend limiting clothing under cause it was hot but it was amazing ... show more

  • 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

  • Excellent fit!
Size: X-Large Color: Giraffe
I was very worried about the sizing of these as I can never find things like this to fit me, how ever, I am a 3-4x in women typically and my husband is a l-xl. I ordered him the xl and my self the 2x. They are both very roomy!!!! We both could actually stand to go down a size, but as these are costumes we like the roomier feel so we can layer up. My only criticisms are it is not a zip up, and the buttons aren't secured well and I feel like the white "stomach" part is a bit much in all the sizes. But our 7 year old is very excited to go trick or treating as a family of her favorite animals (giraffes!!!) ... show more

  • Runs large
Size: X-Large Color: Red Panda
I loved this costume for our Halloween party. Only problem is it’s huge. I’m 5’4” 210 and ordered an XL. The crotch of this costume was around my calves. I was constantly pulling it up to keep people from tripping over the tail. I could have fit 2 people inside the costume because it was so big around. My advice is order a couple sizes smaller than you think you’ll need. The fabric is definitely quality. It’s really soft and held up well to a standard wash and dry in the washer/dryer. I washed and dried on hot hoping to shrink it but it wasn’t enough to notice. It does arrive squished in clear packaging and thus was super wrinkled. A wash with some wrinkle guard fabric softener and it was great. I loved the costume but be careful on the sizing. ... 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
