What this profile actually tells you
Poppy is Yellowberry's seamless, double-layer everyday style with adjustable convertible straps. The fabric isn't listed on the current product page, so we're leaving that field unknown rather than guessing. Sizes come grouped as XS/S, S/M, and L/XL — different groupings than Ladybug or Pipit use.
Seamless construction is why we've tagged Poppy for T-shirts and sensory comfort. But seamless doesn't mean it'll feel the same as Yellowberry's cotton styles — use Poppy's own chart specifically. If a size range straddles two possible fits, let the actual fit decide, not the label.
