Beginner's Guide to Strapless Bras

If you've never worn a strapless bra before—or your past experiences have been frustrating—this guide is for you. We'll cover everything from the basics of how strapless bras work to choosing your first one and wearing it successfully. By the end, you'll have the knowledge to confidently add a strapless bra to your lingerie collection.

How Strapless Bras Work

In a regular bra, the straps do significant work—they help distribute weight to your shoulders and keep the cups in position. A strapless bra has to accomplish all of this without straps, which means:

• The band does most of the work: In strapless bras, the band provides about 80-90% of support (versus 70-80% in regular bras)
• Grip features keep it in place: Silicone strips inside the band create friction against your skin
• Structure matters more: Boning, underwire, and cup construction provide the shape and lift that straps normally help with

Understanding this helps explain why fit is so critical with strapless bras—there's no room for error when the band is doing almost everything.

Types of Strapless Bras

Standard Strapless Bras

These look like regular bras minus the straps. They have underwire, cups, and a band with silicone grip strips. Best for: most everyday strapless needs, moderate support.

Longline Strapless Bras

Extended bras that reach down to your waist, providing more grip surface and support. Best for: larger busts, events requiring all-day wear, maximum security.

Convertible Bras

Multi-way bras with detachable, repositionable straps that can be worn strapless or in various strap configurations. Best for: versatility, different necklines, those who want options.

Adhesive/Stick-On Bras

Silicone cups that stick directly to your skin with no band at all. Best for: backless outfits, deep plunge necklines, smaller busts (A-D cups).

Bandeau Bras

Simple tube-style bras with minimal structure. Best for: lounging, small busts, underneath structured garments that provide their own support.

Finding Your Strapless Bra Size

Your strapless bra size may not be identical to your regular bra size. Here's how to approach sizing:

Start With Your Measurements

1. Measure your underbust: Wrap a tape measure snugly around your ribcage, right under your bust
2. Measure your bust: Measure around the fullest part of your bust
3. Calculate the difference: The difference between these measurements determines your cup size

Consider Sizing Down in the Band

Many women find success by going down one band size (and up one cup size to maintain the same cup volume) in strapless bras. For example:

• Regular bra: 12C → Strapless: 10D
• Regular bra: 14DD → Strapless: 12E

The tighter band compensates for the lack of straps. Try your regular size first, but be prepared to experiment.

In-Store Fitting is Valuable

For your first strapless bra, consider getting professionally fitted. Many Australian department stores and lingerie boutiques offer free fitting services. A professional can assess your shape and size, recommend styles suited to your bust, and help you understand what a proper strapless fit should feel like.

What to Look for When Shopping

Essential Features

• Wide silicone grip strips: The wider the strips, the more grip surface—look for strips that span most of the band width
• Multiple hook-and-eye rows: At least 3 rows give you adjustment room and better support
• Sturdy underwire: Provides lift and shape; essential for C cup and above
• Quality construction: Smooth seams, reinforced edges, no loose threads

Nice-to-Have Features

• Side boning: Adds stability and prevents rolling
• Moulded cups: Provide smooth shape under clothing
• Convertible straps included: Adds versatility
• Matching colour to your skin tone: Nude tones that match your skin are most invisible under clothing

How to Put On a Strapless Bra

Proper technique makes a significant difference in how well your strapless bra stays in place:

1. Start with clean, dry skin: No lotion or oils in the band area. Shower, dry thoroughly, and wait 10 minutes before applying.
2. Hook the bra on the tightest comfortable setting: The band should feel snug—tighter than your regular bra feels.
3. Position the band: Make sure it sits level around your torso, not riding up at the back.
4. Lean forward and scoop: Bend at the waist and use your hand to scoop breast tissue from your sides and underneath into the cups.
5. Stand and adjust: Ensure the underwire sits flat against your ribcage and cups fully contain your breast tissue.
6. Check the fit: The centre gore should lie flat against your chest. There should be no gaping at the top of cups.
7. Do the arm test: Raise both arms overhead. If the bra shifts more than 1-2 cm, it's too loose.

Your First Time Wearing a Strapless Bra

Start at Home

Don't wear your new strapless bra to an important event for the first time. Wear it at home for a few hours to:

• Check how it feels over time
• See if it stays in place during normal activities
• Identify any comfort issues
• Let the bra mould to your body shape

Gradually Increase Wear Time

Build up from 2-3 hours to full-day wear over several sessions. This breaks in the bra and lets you assess performance without the pressure of an event.

Test With Your Outfit

Before the occasion you're preparing for, wear the bra with your actual outfit and move around—sit down, reach up, bend over, dance if that's what you'll be doing. Make sure it stays put through all movements.

Troubleshooting Common Beginner Issues

"It keeps slipping down"

Solutions:

• Try a smaller band size
• Make sure skin is completely clean and dry
• Check that the band is level (not riding up at back)
• Consider a different style with better grip features

"It's uncomfortable"

Solutions:

• If the band feels too tight, try your regular band size (you may need to size up in cups to compensate for less support)
• If underwire digs in, the cups may be too small or the wrong shape for your breasts
• Try a different brand—cup shapes vary significantly between brands

"The cups gap at the top"

Solutions:

• Try a smaller cup size
• Look for demi or balconette styles that sit lower
• Ensure you're scooping breast tissue into cups properly

"I spill over the top"

Solutions:

• Try a larger cup size
• Look for full-coverage cup styles
• The band may be too tight, pushing tissue upward

Building Confidence

If past strapless bra experiences have been discouraging, remember:

• Strapless bras require more attention to fit than regular bras—past failures were likely fit issues, not inevitable problems
• Quality matters more in this category than almost any other lingerie type
• Most women who "can't wear strapless bras" simply haven't found the right size and style yet
• Modern strapless bras have much better grip technology than those from 10-20 years ago

Take the time to find the right fit, invest in quality, and practice wearing your bra before important occasions. With the right approach, strapless bras can become a reliable part of your wardrobe.
