The Ultimate Bra Fit Guide for Every Style

Welcome to the Wingslove Fit Guide! If you've ever found yourself asking, "what's my bra size?", or wondering why different bra sizes seem to fit so inconsistently across various styles, you've come to the right place. This guide is here to demystify exactly how do bra sizes work, helping you find the perfect, most comfortable fit for every single piece in your wardrobe.

How to Measure Your Bra Size Accurately

Getting the right measurements is the first step to finding your perfect fit. Here’s how to do it in three simple steps:

Step 1: Measure Your Band Size (Under Bust)

While wearing a non-padded bra, wrap a measuring tape snugly around your ribcage, directly under your bust. Make sure the tape is level all the way around and parallel to the floor. Round to the nearest whole number in inches.

Step 2: Measure Your Bust Size (Over Bust)

Wrap the measuring tape loosely around the fullest part of your bust. It should be comfortable, not tight. Again, ensure the tape is level and round to the nearest whole number.

Step 3: Calculate Your Cup Size

Now, it's simple math:

Bust Measurement - Band Measurement = Your Cup Size Difference

Once you have that number, you can use a size chart to find your cup size. But for an instant and precise result, why not let us do the work?

Example: If your band measurement is 34" and your bust measurement is 38", the difference is 4". Your perfect bra size is a 34D.

T-Shirt Bras: Your Baseline for a Perfect Fit

What is a T-shirt bra?

A T-shirt bra is your secret to a seamless silhouette. It's designed with smooth, molded cups that are invisible under clothing, especially thin or tight-fitting tops. Its goal is to provide a natural, rounded shape with no visible lines or bumps, making it an essential for everyday wear.

How do I find the right size for a T-shirt Bra?

Finding the perfect fit comes down to a few key checks. Here’s what to look for:

• The Band: It should be snug and level across your back, fitting securely without digging in. If you can comfortably fit two fingers underneath, it's just right.
• The Cups: Your breasts should be fully contained within the cups with no gapping at the top or spilling out at the sides. A smooth line from the cup to your body is the goal.
• The Straps: Adjust them so they sit comfortably on your shoulders without slipping down or digging into your skin. They should only provide about 10% of the support—the band does the rest!
• The Center Gore: The piece of fabric between the cups (the gore) should lie flat against your sternum without any gaps.

The best way to start is by getting an accurate baseline. Use our Bra Size Calculator to find your true size, then select the corresponding T-shirt bra. You can also explore our full collection and use the "Filter" function to find the perfect style for you. You can also refer to the specific T-shirt bra size chart on the product page for detailed guidance.

Push-Up Bras: Understanding the Fit and Function

How do push up bras work?

Push-up bras are designed with padding at the bottom or sides of the cups to lift your breast tissue upwards and inwards. This creates a fuller appearance and enhanced cleavage. At Wingslove, our push-up bras come in different lift levels to help you achieve your desired look:

• Level 1: Gentle Lift. This style provides a subtle lift for a naturally enhanced shape. It's perfect for those who already have full or semi-full busts and just want a little extra definition.
• Level 2: Moderate Lift (Adds One Cup Size). Offering a noticeable boost, this level adds approximately one full cup size to your natural shape. It's an ideal choice for semi-full busts looking for more volume.
• Level 3: Maximum Lift (Adds Two Cup Sizes). This is our ultimate enhancer. Designed for smaller cup sizes or anyone craving a dramatically fuller look, this level adds about two cup sizes for maximum impact.

How should push up bras fit?

Finding the right fit is crucial for both comfort and effect. Because the padding takes up space in the cup, our top recommendation is to go up one cup size from your regular T-shirt bra size. For example, if you're a 36C, try a 36D in our push-up styles.

To find your perfect starting point, use our Bra Size Calculator. Once you have your recommended size, you can explore our collection and use the "Filter" function to find the perfect push-up bra for you. You can also refer to the specific push up bra size chart on the product page for detailed guidance.

Minimizer Bras: The Secret to a Streamlined Silhouette

What is a minimizer bra?

A minimizer bra is a style specifically engineered to reduce the forward projection of your bust, creating a visually smaller and more streamlined silhouette under clothing. It's the perfect solution for preventing button-down shirts from gaping.

How does a minimizer bra work?

It's not magic, it's smart design! Rather than simply compressing your chest, a minimizer bra works by:

• Redistributing Breast Tissue: It gently redistributes breast tissue more evenly across your chest wall and towards the sides, rather than pushing it forward.
• Using Non-Stretch Cups: The cups are made from firm, non-stretch fabric that holds your shape securely, preventing bounce and providing a compact profile.
• Offering Full Coverage: Fuller, wider cups provide excellent coverage to prevent any spilling, ensuring a smooth look from every angle.

How do I choose the right size for a minimizer bra?

This is the most important part: you should choose your true, regular bra size. A minimizer bra is already designed to achieve the slimming effect, so sizing down will only cause discomfort and a poor fit.

Start by finding your accurate measurements with our Bra Size Calculator. Once you have your size, you can confidently shop our collection. You can also refer to the specific minimizer bra size chart on the product page for detailed guidance.

Sports Bra Sizing: Where Support Meets Comfort

How do I know if my sports bra fits correctly?

A great sports bra should feel slightly snugger than your everyday bra, but it shouldn't be restrictive. The key is finding a secure fit that minimizes bounce without sacrificing comfort. Here are the golden rules for sports bra sizing:

• Don't automatically size down! While a firm fit is essential, choosing a size that's too small can restrict breathing and cause discomfort.
• Your body changes, and so does your bra size. Factors like weight fluctuations, hormonal changes, and pregnancy can all affect your size. We recommend measuring yourself every time you buy a new sports bra.
• Start with your current size. Your regular bra size is the best starting point. For an accurate measurement, use our Bra Size Calculator to find your most up-to-date size.

How do I find the right sports bra for my activity?

Beyond size, the most important factor is matching the bra's support level to your activity's impact level. Sports bras are generally categorized into three levels of support:

• Low-Impact Support: Perfect for activities like yoga, walking, and stretching. Provides gentle support and maximum comfort.
• Medium-Impact Support: Ideal for activities like light jogging, cycling, and hiking. Offers a balance of compression and comfort.
• High-Impact Support: Essential for high-intensity activities like running, aerobics, and mountain biking. Delivers maximum support to prevent excessive movement and discomfort.

Pro Tip: Women with larger busts may prefer the security of a high-impact bra even for lower-impact activities. Ultimately, the best sports bra is one that fits perfectly, feels comfortable, and matches your personal style. You can also refer to the specific sports bra size chart on the product page for detailed guidance.

Strapless Bra Sizing Guide: The Secret to a Secure, Strapless Fit

What's the right way to do strapless bra sizing?

A great strapless experience is all about a super-secure band. Since there are no straps for support, the band has to do all the work. For this reason, we highly recommend using the "Sister Size" rule for the perfect fit:

Go DOWN one band size, and go UP one cup size.

For example, if your regular T-shirt bra size is a 36C, your ideal strapless bra sizing will likely be a 34D. This ensures the band is firm enough to stay in place all day without slipping.

Can strapless bras actually support larger busts?

Absolutely! We've designed our strapless bras with the support you need in mind. Here’s how:

• Supportive Fabrics: We use high-quality, structured materials that provide excellent lift and hold.
• Anti-Slip Silicone Grips: A premium silicone grip lines the edges of the band and cups, ensuring the bra stays securely in place without any slipping.
• Comfort-Driven Design: Our strapless bras are crafted to feel snug without being restrictive, so you can confidently rock your shoulder-baring outfits. The skin-friendly materials ensure you feel free and comfortable.

Is it versatile?

Yes! Every Wingslove strapless bra comes with a set of detachable straps. This means you can wear it as a traditional bra too, making it a versatile and valuable addition to your lingerie collection, not just something for special occasions. You can also refer to the specific strapless bra size chart on the product page for detailed guidance.

Understanding Bra Sister Sizes: Your Secret Weapon

What are bra sister sizes?

Bra sister sizes are alternate sizes where the cup volume stays the same, even though the band size and cup letter change. It’s a simple trade-off system that can unlock your perfect fit.

The golden rule is:

• When you go UP one band size, you go DOWN one cup letter.
• When you go DOWN one band size, you go UP one cup letter.

For example, a 34C has the exact same cup volume as a 36B and a 32D.

When should I use sister sizing?

Sister sizing is your best friend in a few common situations. It's the perfect tool to use when you find a bra where:

• The cups fit perfectly, but the band is too loose.
  Solution: Go down one band size and up one cup size (e.g., from 36C to 34D).
• The cups fit perfectly, but the band is too tight.
  Solution: Go up one band size and down one cup size (e.g., from 36C to 38B).

This technique is incredibly useful when your body fluctuates due to hormonal changes or weight changes, helping you fine-tune your fit. Ready to find yours?

Check out the bra sister size chart below! Find your current size, then look to the left or right to discover your sister sizes.
