16 Reasons My Bra Strap Falls Off the Shoulder

What's more annoying than wearing a bra? ​Being out all day and having to deal with the effects of when bra straps fall down. Having your straps make an unannounced appearance ​right around your elbow was probably not what you were envisioning when you put on your outfit, but what's a girl to do? Here are 16 reasons your straps might be falling down, and a few solutions to the challenge.

​16 Reasons My Bra Strap Falls Down

​1. Loose Straps

​For such an obvious reason, it can often be overlooked! When you first get a bra, you likely adjust the straps to properly fit. After this initial time though, how often do you actually resize the straps? Wearing your bra, along with it going through the wash, can naturally loosen the straps over time.

When checking to see if your straps are the proper length, they should adhere to a two-strap tension rule. This means you can still insert two fingers between the straps and your shoulder without much resistance.

​2. Straps are Too Long

Some bras might not offer much leeway for the strap adjuster to move. If you're a bralette lover and enjoy styling outfits with bralettes, you might even find there's no flexibility on the strap length at all! Even when the straps are in their shortest length, they could still be too long to be kept in place.

​3. Short Torso

​There's no winning here when you've got a short torso. The length between your breasts and shoulder might not be enough to fill the length of the strap. Try a different bra size, because you might need a smaller one to fit you better!

​4. Petite Body Frame

​If you're petite, you'll have to exert extra effort to find brands which offer petite sizes. They're not as common. If you take the extra steps in finding them, your bra straps are less likely to fall off.

​5. Disproportionate Body Parts

You've heard about one boob being bigger than the other, right? It's natural. So is one leg or one arm being shorter than the other, causing your stance to be disproportionate as well. This may be why your bra falls. It could also be why the issue is always just that same strap, all the time.

​6. Hunched Posture

As the day goes, the tightness of your bra may make you subconsciously hunch over. This can make the straps loosen up in front and fall off. If you catch yourself hunching over, make an effort to stand up straight.

​7. Scoliosis

​For those who suffer from scoliosis, bra straps can be your worst nightmare. The condition sometimes makes your shoulders uneven so the lower one might see that your bra strap falls off shoulder.

​8. Narrow Shoulders

​Some women have wider shoulders than others. Other women have narrower shoulders than average. Most bras have a wide range of options when it comes to the size of the cup and band, but rarely the straps.

It's hard to find a bra with a sufficient cup but closer straps. Try looking for a bra with a j-hook. Most convertible bras have this, and it can help keep your straps up and hidden.

​9. Downward-sloping Shoulders

​In a similar way, women whose shoulders are sloped downwards will have a harder time keeping their straps in place. On your non-dominant side especially, there's a bigger tendency that the bra strap slips off one shoulder.

​10. Big Bra Cups

Sagging is a real issue. As you age, the breasts eventually surrender to the force of gravity. They lose the ability to perk up on their own. This creates a gap on top of your cups, which may be why bra straps fall off shoulders. When this happens, it's good to find a supportive bra, like one from our recommended underwire push up bras guide.

The more coverage a cup has on your boob, the less likely that your straps will slip. This is because the strap will sit closer to your neck, thus making it harder to slip off. If you  don't want to deal with your straps falling off of your shoulders all day, try wearing a shelf bra for ease and comfort.

​11. Bra Extenders

​From the name itself, you can already see where the problem might stem from. Bra extenders are used to lengthen the band of your bra if you need additional inches. The issue with this is that it sets your straps farther apart, thus increasing the chances of them falling off.

​12. High Band at the Back

​You'll know you're wearing your bra right when the band at the back wraps straight around underneath the shoulders. If your bra sits too high on your back, you're at risk for strap slippage.

​13. Loose Band

​Do you think a bra fits right just because it stays in place when you snap it together at the back? Sometimes even when the band seemingly fits, you still need to size down. It's not about just fitting. The band needs to be snug around your body, so the straps will also stay in place, much like a bandeau.

​14. Wrong Bra Style

Just as there's a right style of clothes for your body shape, there's also bra styles for every body type. If your straps are slipping and sliding, consider trying a different style bra. If your straps are really bothering you could try converting your bra into a strapless one!

​15. Loose Elastic

The elastic in your bra is not made to last forever. As you wear a bra over and over, the elastic on the straps are bound to stretch out. As much as you love that 8-year-old bra, it's probably time to trade it in for a tighter model.

​16. Old Bra

​Speaking of 8-year-old bras, when your bra is too old, there's nothing much you can do. The band rides up, the cups can't hold up your breasts, and the bra straps basically live by your elbow.


Knowing the reasons will keep you from questioning over and over, why do bra straps fall off shoulders. It's a common thing that can happen to anybody, but it's not without resolutions. Knowing these reasons, you won't find yourself in a curious situation the next time it happens.
