SISTER SIZING

Sister sizing allows you to find your perfect fit. Sometimes after measuring yourself it is possible that your size may still need to be adjusted.

The following chart shows sister sizing for each bra size. All of the sister cups in the same row are the same size.

Sister sizing is like a seesaw. If you move up in the band, move down in the cup and vice versa. For example if you find that a size 34E fits well in the cup, but is too big around the band, go down to the next sister size in the row and try a 32F.

The Hotmilk Ambition is a wirefree T-shirt nursing bra built for everyday wear — smooth enough to disappear under fitted tops, supportive enough to actually wear out of the house. The standout feature is the magnetic nursing clips: one motion, one hand, done. No fumbling with traditional clips while holding a baby.

Features

  • Magnetic nursing clips — the fastest nursing access in the lineup, one-handed and effortless
  • A-frame mesh nursing support — discreet access with structure that holds its shape
  • Smooth plunge contour cup with light padding — no-show under T-shirts and fitted layers
  • Wirefree construction with medium support — comfortable for all-day wear without underwire pressure
  • Non-roll sheer striped band — stays in place without digging or riding up
  • Versatile straps — wear standard or convert to racerback depending on what you're wearing
  • Rose gold hardware — a small detail that makes it feel less utilitarian
  • 6-hook back closure — more support and adjustability across the back

⚠️ Magnetic nursing clips are not suitable for mothers with a pacemaker or defibrillator.

Best For

  • Wearing under T-shirts, fitted tops, and everyday layers
  • Out-of-the-house days when you want medium support and a smooth silhouette
  • Nursing on the go when speed and discretion matter
  • Pregnancy and postpartum everyday wear

Materials Nylon, elastane, cotton, polyester, polyurethane

Care

  • Machine wash cold, gentle cycle
  • Use a lingerie wash bag
  • Line dry in the shade
  • Do not tumble dry
