Underbust Band Size Chart
Super Simple Sizing
Many of my bralettes come in three cup size categories: Petite Cup (A–C), Full Cup (D–E), and Extra Full Cup (F–G). Once you know your cup category, just find your band size — that’s all you need!

Once you have your cup size use the chart below to find your band size and follow the row to see your Eco Intimates size.
FYI: Our bra bands have around 20% stretch, offering a flexible, comfortable fit. The chart below shows each band’s flat measurement, maximum stretch, and the ideal underbust range for best support. This helps you compare your existing bras to the sizing of my range.
