Knowing your bust is the first step to loving your body. Every woman is unique, and the same goes for her breasts: no two are alike. Yet, many women still feel insecure or confused about their shape, their size, or which bras truly suit them.
From the changes experienced during adolescence to transformations like pregnancy, our bust size is constantly evolving, and adapting to these changes is key to feeling comfortable, confident, and authentic.
In this guide, we'll help you identify your bust size—small, regular, or large—so you can choose the perfect bra and start looking (and feeling) the way you truly deserve: with confidence and comfort.
Small bust
If your bust is small, flat on top, and separated in the center, you probably wear an A or B cup. While finding the perfect bra can seem difficult, there are silhouettes that are ideal for you.
✅ What DOES work:
- Bralettes: Comfortable, lightweight, and stylish, they offer a natural fit without heavy construction.
- Half cup or light coverage: smaller cups that fit well and avoid excess space.
- Push-up bras: add volume and shape without losing naturalness.
❌ What DOESN'T work:
- Deep or full cups : the bust does not fill them, which creates spaces and a poor fit.
- Highly structured bras : You don't need extra support, so avoid unnecessary underwires and underwires.
Tip: Look for bras designed for your bust size, not the other way around. Comfort and a proper fit make all the difference.
Medium or regular bust
This type of bust is usually a B cup, with balanced volume and a rounded shape. If this is your case, you have the advantage of almost any bra that fits you well! You just need to choose based on your style and what makes you feel most comfortable.
✅ What DOES work:
- Triangular silhouettes : both half-cup (more cleavage) and full-cup (greater coverage) fit perfectly.
- Balconette : ideal if you're looking for a straighter, more striking neckline. They fill out the cup well and enhance the shape of the bust.
❌ What you should consider:
There are no hard and fast restrictions, but choosing based on the occasion and your preference (more coverage or more cleavage) is key to feeling comfortable and confident.
Tip: Explore different styles and fabrics. Your bust shape is very versatile, so take advantage of the opportunity to find what flatters you best.
Large or very large bust
This bust has volume in all areas: center, sides, top, and bottom. Being heavier, it requires bras with reinforced support and specially designed structures to support it comfortably.
✅ What DOES work:
- Deep, full cups : they envelop the entire bust, preventing spills and improving security and shaping.
- Wide bases and backs : offer real support all day long without discomfort.
- Thick straps : distribute the weight and prevent marks on the shoulders.
❌ What DOESN'T work:
- Unstructured and unwired silhouettes : They don't offer the necessary support, can cause the bust to look saggy, or cause the bra to roll down.
- Bralettes and thin straps : These are generally not designed for heavy busts and can be uncomfortable.
