Long skinny baby... best clothes?

Lauren

My almost ten week old baby boy is super long and skinny. He was 97th percentile length at his 2 month visit (24.5 inches!) but only 12th percentile weight. His 0-3clothes are getting snug because of length but 3-6 are sooo roomy around his torso.

My question- anyone have suggestions on brands that fit long skinny babies well? Gap and old navy are way too short. Carters seems to be the best for onesies. Hanna Anderson is great for one piece footies. I haven’t found any brand with long enough pants that won’t fall off his skinny hips.

Any other ideas? We are in the USA.
