happy you like them

first: no meshes is needed, because it's sort of "built in". and make sure you DON'T have other infant meshes or outfits installed. also make sure sim/object detail in the graphics settings is on high, or it will not show up correctly (they're supposed to look exactly like the picture I've posted. the colour may vary some because of lighting in the game, but the shape of the outfits is correct in my pictures)
and only put in ONE outfit. if you put in more than one, they will conflict with each other, or only one of them shows up.
I put them where I can easily find them, in the downloads folder. some likes to use a defaults folder, but everything I put into my downloads folder works perfectly.
if you have problems with certain outfits, try PM me a picture of them. then it's easier for me to see if something is wrong.
