    I’ve been anticipating for this onesie to come in and it finally did 5 days after I first ordered it! This is my first onesie I bought from this company and I have to say it’s one of the most comfortable things I ever worn. I’m 5’2, 110lbs and ordered a small which fit perfectly. I love the way the shoulder is hemmed over giving it more of a “baby” onesie look. It gets very hot where I live in the summer and this is light enough for when it gets hot. The fabric is super soft and stretchy. The only thing I have to say is the crotch buttons are plastic so when undoing them be careful not to be too hard with taking them off. I can’t wait until this company releases more onesies with more cute designs, which I plan to buy in the near future!

    This onesie is terrific. It’s very well made in a quality stretchy cotton fabric. The print is really cute, with lots of animals like hippos, giraffes and turtles, trees and clouds, and ABC letters. The blue trim is really babyish. I got the XL size for a 40 chest and 180 lbs. The fabric is a little stretchy so it gives you some flexibility in sizing. The XL fits me snug but with stretch to spare, even when diapered. The three snaps are very strong and getting them undone can be quite a challenge! It says in the item description that it will shrink a little in the first few washings. I have washed it once and it did not shrink much.

    The cut is somewhat biased to the female form. For a man, the shoulders are a little snug, the chest a little loose, and the legs “girl-leg”. But this bias is minor and should not dissuade a man from trying this out. Altogether, this is a fun and practical item for any ABDL.

    Littleforbig has done it agains!!! This onesie is super duper great!!! It fits the body like a glove and is so cute!! It’s soft and doesn’t irritate my skin. Just like the dinsoaur onesie, it has plastic snaps, which I like, however they are a bit hard to undo so always unsnap them from the button to avoid any possible tearing. And the shipping price doesn’t cost an arm and a leg like so many abdl companis charge!!! If you’re considering a onesie, you should definitely jump on a littleforbig one 🙂

    I love this onesie so much and I would live in it if I could. It’s my favorite. I was a little wary buying this after ordering another from a different brand and having the small look like an extra large. But when I got this onesie and tried it on it fit me just right (being a small little is hard sometimes because a lot of products aren’t made for a small size) and it makes me feel so little and cute. I will definitely be buying more onesies from little for big. They’re a good price, shipping is fast and it did not disappoint!
