Understanding Sizing Types

Not every style sizes the same way. Here's how each one fits, so you can choose the right size.

A stretch cup that moves and grows with you. No fixed cup shape: one size stretches across 2–3 cup sizes as your body changes.

  • Wire-free, seamless stretch fabric
  • Adapts up or down 2–3 cup sizes
  • Sized by band with a cup range, not one fixed cup

Best for: the most flexibility as your size changes

A shaped cup built to fit comfortably across two cup sizes (e.g. B/C, D/DD, E/F), not one exact size.

  • More structure and support than FlexFit
  • Covers the "in-between" without a full refit
  • Still sized by band and cup, just labelled as a pair

Best for: when you're unsure of your size or it's changing

Traditional single band and cup size (e.g. 10D). Fits exactly as measured.

  • Fixed cup shape and volume
  • Highest level of shape and support
  • Best accuracy for fuller busts

Best for: when you know your size and it's stable

Every Hotmilk bra has some cup flexibility built in to handle day-to-day changes. These three types just differ in how much.

Quick guide: Want the most flexibility? Start with FlexFit. Not sure of your size, or it's changing? Try Dual Cup. Know your size and it's stable? Go Cup Sized for the best fit.
