What this profile actually tells you

Poppy is Yellowberry’s seamless, double-layer everyday style with adjustable convertible straps. Fiber content is not stated on the current source page, so this profile leaves it unknown. The published size groups are XS/S, S/M and L/XL—not the same rows as Ladybug or Pipit.

Seamless construction is why Poppy is tagged for T-shirts and sensory comfort. Seamless does not mean “one size will feel the same as another Yellowberry cotton bra.” Use the Poppy chart only. If grouped sizes land between two bodies, fit—not the label—decides.
