Have you tried the custom-made stuff from some the YT members? Sonja at Pocomutt makes adorable outfits and pajamas and since you send her your measurements they will fit perfectly (and not cost any more than other sizes). I think her prices are extremely reasonable! Go Fetch, ChloeBella and Tinkerbell's Closet have tons of cute stuff too! Those are just the sellers I have used so far. I know there are tons of others on here too!
Good luck!
