Not trying to provide an ad for them, but I have purchased several items from them. They have been of outstanding quality and very good to work with. The materials and craftsmanship is very good.
I have several custom made onesies, satin covered plastic pants, fleece onesies, rompers and other items purchased from this company. For the most part, I have been more than satisfied with their products.
Just make sure that you have communication with them about any questions for size on custom made products.
Otherwise, yes, they are a very legit company. Very discrete, and very willing to work with you in customizing your clothing to your desires and needs.
