Choosing the right bra can be an overwhelming task, especially with the countless options available in the market today, each with many names, such as underwired bras, wireless bras, nursing bras, and crop tops, to name a few. We won’t even go down the path of bra sizes (6-36) and cup sizes (A-KK).

One common dilemma many women face is whether to opt for a wired or wireless bra. Both bras offer unique benefits and drawbacks. Understanding the differences between them is crucial in making an informed decision. In this article, we’ll explore the pros and cons of underwired bras vs wire-free bras, debunk some common myths, and provide insights to help you find the perfect fit.

Pros and Cons of Underwired Bras

What is an Underwired bra?

Underwired bras feature a thin, flexible wire sewn into the bottom of the cups. This wire helps provide additional support and shape to the bust.

Here are some examples of underwired bras.


  • Enhanced support and lift, especially for larger busts
  • Defined shape and contouring
  • Ideal for wearing under structured garments like dresses and blouses.


  • Potential discomfort or poking if not correctly fitted.
  • May dig into the skin, irritating.
  • Some women find under-wired bras restrictive or uncomfortable to wear for extended periods.

Pros and Cons of a Wireless Bra

What is a Wireless bra?

A wireless bra, also known as wire-free and non-wired, forego the underwire and rely on other methods for support, such as a wider band and strategically placed stitching, to provide support.

Here are some examples of non-wired bras.


  • Increased comfort, especially for everyday casual wear
  • Reduced risk of skin irritation or discomfort
  • Greater flexibility and freedom of movement
  • Ideal for casual wear, lounging, or activities like yoga


  • Provide less shaping and support when compared to underwired bras, especially for larger cup sizes.
  • May not provide enough lift or separation for some women.
  • Limited options for structured or formal attire.

When should girls wear Underwired Bras?

This largely depends on individual comfort and development. Under-wire bras provide additional support and shaping, making them suitable for those who have developed breasts or need extra support during physical activities. Typically, girls may consider wearing underwired bras when they notice discomfort or lack of support with non-underwired styles. However, ensuring the bras are correctly fitted is crucial to prevent discomfort and potential health issues. Ultimately, wearing underwired bras should prioritise comfort, support, and personal preference, allowing girls to feel confident and comfortable in their clothing.

Do underwired bras prevent sagging?

Contrary to popular belief, no conclusive evidence suggests that wearing underwired bras prevents sagging. Sagging is a natural process influenced by genetics, age and lifestyle. While underwired bras may offer temporary lift and support, they do not halt the effects of gravity or aging.

Are Non-Wired bras better than Underwired bras?

The debate over whether wireless bras are superior to wired bras has been ongoing for years, with opinions varying widely among individuals. Non-wired bras offer a sense of freedom and comfort, allowing for unrestricted movement throughout the day. They are often favoured for their ability to gently support without the potential discomfort or digging frequently associated with underwire designs. Additionally, a wireless structured bra is typically more versatile and suitable for a range of activities, from lounging at home to shopping or engaging in light exercise.

On the other hand, wired bras are praised for their ability to offer structured support and shaping, particularly for individuals with larger busts. The underwire provides added lift and definition, contributing to a more polished silhouette. However, some argue that poorly fitted wired bras can cause discomfort, poking, or even long-term health issues.

Ultimately, the choice between non-wired and wired bras boils down to personal preference, body type and lifestyle demands.

Why do Nursing Bras Not Have Underwire?

Nursing bras are designed to accommodate fluctuating breast sizes during pregnancy and breastfeeding. Underwires can compress or restrict milk ducts, leading to discomfort or potentially clogged ducts. Therefore, nursing bras typically feature soft, stretchy fabrics and adjustable straps for optimal comfort and functionality.
