I just checked and the Louisdog granny chic tee I got for Latte is a size Small. it fits her perfect.
each louisdog piece has its own sizechart. some of them do vary slightly.
the measurements on this tee is length 7 1/2 , girth 11 1/2 and the neck is roomy.
its hard for me to say what size Ella would be. ( I don't want to say get the XS and then it be too small and i'd feel bad ). but this one here in size small fits Latte perfect. i'm thinking the neck would be too roomy for ella in the small. and even the girth may be too roomy for Ella cause its slighty roomy on Latte. the length is perfect. it fits like a little dress
I haven't rechecked the size chart to see if these measurements are the same as what they posted. i'll go do that now
I just checked the sizechart and compared the measurements I got. the ones I got were alittle smaller so I remeasured them again. there measurements were accurate. the girth is 12 inches, and the length is 8. 3 inches. so, it is true to size. ( if anything ... it may actually be a tiny bit smaller than they say but def. the item is not bigger than they say ). so, I would guess Ella would be a size XS but I cant say for sure... I wouldn't get an all in one though. those are so hard to get the right size .
