How to Choose the Right Bra Size? (Step-by-Step Guide)

Why Is the Correct Bra Size So Important?

An ill-fitting bra compromises both comfort and posture, and can even prevent your most beautiful outfit from looking chic. The correct size, however, enhances support, lifts the breasts, and keeps you comfortable all day long. Good news: finding the right size is easier than you think. You can find your own size at home in 2 minutes with a measuring tape, following the steps below.

Bra Size Consists of Two Measurements

Bra size consists of two pieces of information: a number (band size) and a letter (cup size). For example, 75B: here 75 is the band measurement, and B is the cup size.

1. Band Size (Number)

Hold the measuring tape parallel to the floor, just under your bust and around your back. Exhale and take the measurement. The resulting centimeter value gives you your band size (e.g., 73–77 cm → size 75).

2. Cup Size (Letter)

This time, wrap the measuring tape around the fullest part of your bust. Subtract your band measurement from this measurement. The difference determines your cup size:

  • ~12–13 cm difference → A cup
  • ~14–15 cm difference → B cup
  • ~16–17 cm difference → C cup
  • ~18–19 cm difference → D cup

4 Signs of a Well-Fitting Bra

  • The back band lies flat: It doesn't ride up, ideally it's parallel to the floor.
  • The underwire doesn't dig in: In an underwired model, the wires encircle the breast but don't leave marks.
  • The straps don't cut into the shoulders: If they leave marks or constantly fall down, the size or adjustment is incorrect.
  • The cup is full: There's neither spillage nor gaping.

Bralette or Underwired Bra?

A bralette set is a model without wires or with light support, offering maximum comfort all day; it's ideal for daily wear and small–medium cup sizes. An underwired bra provides more support and a lifted appearance; it's suitable for all cup sizes and preferred for special outfits.

What to Do If You're Unsure?

If you're between two sizes, it usually helps to try the smaller size for the band, and the larger size for the cup (e.g., 75C instead of 80B). Most Luveà sets are true to size, meaning you can choose your normal size; you can also confirm with the Luveà size chart and measurement guide on each product page.

Once you've determined your correct size, you can choose the most flattering one for you from the bralette sets and all collections. All orders are delivered to your door with discreet and private packaging, and fast shipping.
