How to choose your bralette size – step by step

Jak dobrać rozmiar braletu – krok po kroku

Comfortable underwear is our thing – but for it to be truly comfortable, it also has to fit well. And we know that can be a challenge. Our bodies change with the seasons, the cycle, hormones… and what we wear closest to our skin matters most. At myUnds, we make underwear without wires or extras – designed to adapt to you. Before you shop, here’s how to find your perfect bralette size.

Types of bralets

We’ve created four different bralette styles to meet different needs. Ask yourself: Do you want more support? Total freedom? A smooth look under clothes? Or all-day comfort for movement?

  • Rui –classic triangle bralette with adjustable straps and a soft band under the bust. Perfect under a t-shirt – especially in smooth, invisible cotton.
  • Via – with longer cups that narrow towards the shoulders, and a joined bottom for better hold. A great choice for fuller busts and nursing mothers.
  • Mia – a “top-style” bralette without separate cups. Sporty, keeps everything comfortably in place.
  • Maya – no clasp, slips on over the head. Wide band and straps offer gentle support without pressure. Available in sizes from XS to 6–7XL..

Types of fabrics

All our fabrics are certified, soft, and skin-friendly – but each behaves a bit differently:

  • Smooth GOTS cotton – soft and flexible; less stretchy than ribbed cotton. Not see-through..
  • OEKO-TEX Standard 100 ribbed cotton – soft, slightly thicker, very elastic; adapts well to the body and bounces back. Not see-through.
  • Openwork pointelle cotton OEKO-TEX Standard 100 – our softest; stretchy but less springy. Airy, thanks to its openwork texture. Incredibly gentle on skin.
  • Tencel™ OEKO-TEX Standard 100 – a silky plant-based fibre made from wood pulp (modal); thin, smooth, and breathable. Perfect even for sunbathing.

Which bralette size to choose? (step by step)

  1. Measure your underbust
    Place the tape measure snugly under your bust, exhale, and note the measurement.
  2. Measure your bust
    Wrap the tape around the fullest part of your bust (over the nipples), without tightening it.
  3. Find your size in the chart
    Use our size chart to match your underbust (top row) and bust (left column) – your size is where the two meet.

PRO TIP: If you’re between sizes:
– Go down a size if you like a snugger fit or more support.
– Go up a size if you prefer more freedom and no pressure.IStill have doubts?
