Thank you

I’ve bought quite a few of these for my daughter over the years. I really appreciate the great quality and comfort. I always recommend wonsies to anyone looking for big kid/ adult one piece suits.

Very comfy, perfect for those with sensory issues

I wear very high capacity incontinence briefs, and these are perfect for keeping them in place so that they don't sag or chafe. Compared to other brands of bodysuits I've tried, these are very comfortable (the material is wonderfully soft, there's no annoying tags, and while it's not seamless, the seams do not itch or cause irritation like in some other brands), good quality, and good value.

I only have two minor issues, one is that the neck is a bit too snug for my liking, and that when closing the snaps I usually either need my partner to help me, or there's a lot of bending and stretching required (me having a rather large belly doesn't help things; I imagine someone less overweight would probably have fewer issues getting it on by themselves). However considering that I am not in the demographic this was designed for, I can hardly fault it for doing what it's supposed to.

Overall I am very happy with it, and will likely be shopping with Wonsie for all my future bodysuit needs.

Solid Product

I purchased this onesie to ensure that the waist ban of my pull ups aren’t visible at the gym and to prevent nappy sag in daily life. This product works very well for both of these purposes and fits true to size. It is discreet on that it looks like a singlet under a t-shirt. The only change I would make is to get rid of the legs on it. I dislike the sensation of the tighter crotch coupled with the looser legs. Overall, I am impressed and will be ordering again.
