Finding a well-fitting bra is challenging and women with small busts are familiar with those unique issues. Standard bras often have cups that are too deep, while straps and bands tend to be either too loose or uncomfortably tight.
Why Finding the Right Bra Matters
With so many bras designed with a one-size-fits-most approach, smaller chests women are underwhelmed with market offerings. Well fitting bras offer more than just looking pretty. The support and comfort encourages better posture and reduces strain on shoulders and back.

Perfect Fit
Fit matters as bands need to be firm and flush against the torso. Shallow cups encase the breast tissue without gaping. Take the Fit Finder Quiz to find your perfect size and bra styles recommended for your shape.
Half Sizes
25% of women wear a half cup size - do you? No need to compromise if you’re in between sizes. ThirdLove’s proprietary half cup sizes make it possible for everyone to find their perfect fit.
Light Padding or Contour Cups
Light padding gives subtle support and shaping while removable padding allows the wearer to adjust the shape as needed.
