Q Cup Bras: Largest Widely Available Size, with Specialty Options Beyond

In mainstream retail, the largest commonly stocked cup size is Q (US sizing). However:

• Specialty brands (e.g., Elila, Goddess, Panache, Curvy Kate, Bravissimo) offer cups up to K, L, M, N, O in band sizes 28–56.
• Custom-made bras can accommodate any size/shape asymmetry.
• International variance: EU/UK sizing uses different letter progression (e.g., EU Q ≈ US O). Always convert using the brand's chart.

Proper fit requires both band and cup measurement; a Q cup on a 34 band fits very differently than a Q cup on a 48 band. Professional fitting is strongly recommended above DD.
