Some Considerations When Choosing Lion Onesie

Browsing a big collection will be overwhelming unless you have a rough draft of what you are looking for. Depending on the user, your expectations for these cute lion onesies might also change a little bit.

Lion Onesies For Babies

  • Ease of Use
A baby can’t put the onesie on themselves easily and they might not make it easy for you either. Hence, you would want to find a onesie with a double-way zip more than anything. Changing into and out of it will be so much more convenient.
  • Safety & Comfort
Our top priorities in clothes for toddlers are safety and comfort. Long sleeves and covered feet are the optimal features here because they protect sensitive skin, though it means you need breathable materials like organic cotton as well. Furthermore, we also have features such as panel-covered zips, lion paws, and ears without buttons or studs that might hurt the baby. Of course, no choking hazards.
  • Size
Letting the baby wiggle out of the lion onesie is the last thing you want! Therefore, the size should fit firmly and leave little space without being too tight. Babies grow up differently from one another, so age might not be the correct indicator for their size. You will need to measure their weight and height to use our size chart!

Kids Lion Onesies

  • Design
The easy on-and-off closure is no longer a must-have with older kids! They can comfortably handle a themed costume such as the famous Lion King onesie or any of their favorite cartoon characters. There will be more details like the ears and the fluffy tail!
  • Comfort
Cotton and cotton blends are still our best choices because they are comfortable inside out, breathable regardless of the weather, and available in the most vibrant colors. Choking hazards are also not an issue for big kids since they have more awareness of things, but we chose to limit details like buttons and rhinestones. Without them, your kid can enjoy various activities without any discomfort.
  • Versatility
Children would love to use what they love for a wide range of activities, from festivals and costume parties to indoor relaxation. Our soft fabrics and their favorite lion are enough to make a combo that they can’t resist!

Lion Onesies For Adults

  • Fabrics
As adults, you will have more options with the materials of your onesie. Cotton is still the most breathable and comfortable fabric for a onesie that will cover your entire body. But, you can also go for polyester as a lining or an addition if you want the costume to be more durable. You also have the option of an extra layer of fleece, for example, when the weather turns cold and you still want to enjoy the lightweight comfort. It might seem a little childish but your pleasure is the most important thing!
  • Personal style
Who is going to judge you for dressing up with a cute lion onesie? You can opt for the baby lion’s round ears and soft big paws as well – it is entirely up to you. If you enjoy a costume with a realistic appearance, you can try the ones with many details on the head. However, you might also need good makeup for it! Being glamorous with a lion onesie is not impossible either. No one can stop you from styling your hair prettily, holding a trendy purse, and even slipping into your favorite high heels. You can look like a fashionista without compromising your comfort!
  • Functionality
There are onesies you can wear for cosplay parties and ones for personal time. Depending on your purpose, you can choose different fabrics specified for stretchiness & endurance or pure comfort. Avoiding outfits with thick zips and hard studs will also be a good way for you to do a comfortable onesie!
