Not sure where to begin? Start with Bra Fit Basics.
Bra Fit Basics: Start Here
New to bra fitting, or want to make sure you are evaluating a new bra correctly? Start with these videos on putting a bra on, adjusting it, checking fit and narrowing down your best starting size.
How To Put On A Bra
A bra can look like the wrong size before your breast tissue and straps are properly adjusted. Tomima demonstrates the steps she considers important for getting fully into a bra before judging its fit.
How To Find The Best Fitting Bras
A new bra deserves a proper fit check before you decide it does not work. Tomima walks through the adjustments and visual clues she uses to evaluate band, cups, center panel, underwires and straps.
How To Find Your Best Starting Bra Size
Your bra size is a starting point, not a promise that every bra with the same size on its tag will fit the same way. Tomima shows how the fit of the bra you are wearing can help you decide what size to try next.
How Large Cup-Sized Girls Find Their True Cup Size
Larger cup sizes make visual fit checks especially useful. See how breast placement, cup containment and center fit can reveal whether more cup room is needed.
Your Sister Bra Sizes & Your Bra Size Neighborhood
Band and cup sizing work together. Tomima demonstrates nearby sister sizes and explains how moving through your size neighborhood can help when one part of the bra fits and another does not.
Bra Sizing & Measuring Videos
Bra sizing is more than a number and a letter. These videos cover measuring, cup volume, sister sizing, larger cup sizes, international sizing and HerRoom's Universal Cup Sizing™.
Bra Size: How To Measure For The Best Fit
Measuring can give you a useful place to begin, but small details can change the result. Tomima demonstrates how she approaches bra measurements and the factors she wants women to keep in mind.
Mastering The Cup Size Game
A cup letter does not represent one fixed breast volume. Tomima visually demonstrates how cup size changes with band size and why the relationship matters when you shop.
How Large Cup-Sized Girls Find Their True Cup Size
See how positioning all of your breast tissue inside the cups can change what the fit reveals - especially in larger cup sizes.
Your Sister Bra Sizes & Your Bra Size Neighborhood
Learn how band and cup changes work together and why a neighboring size can sometimes improve one part of your fit while preserving similar cup volume.
Plus Size Bra Fitting
Above a D cup, cup letters become less consistent from one brand or country to another. Tomima explains larger-cup naming and the HerRoom sizing tools that make those differences easier to navigate.
How To Find Your Best Starting Bra Size
Tomima uses the way your current bra fits to show what to adjust first and how to move toward a better starting size.
The Difference Between US, EU & UK Bra Sizes
The same cup volume can carry different letters depending on the sizing system. Tomima explains why US, European and UK bra sizes diverge and how Universal Cup Sizing™ helps you compare them.
Bra Styles & How to Choose Them
Different bra styles create different fit, coverage, support and appearance. These videos explain what Tomima looks for and the styles or features she recommends for particular bodies, wardrobes and results.
Bras For Women With Small Cup Sizes
Small cup sizes require close attention to breast placement, cup shape and proportion. Tomima discusses the two very different goals many small-busted women have and the bra features she recommends for each.
Bras for Strapless, Backless and Low-Cut Dresses
Strapless, backless and low-cut clothing create different support and coverage problems. Tomima walks through the lingerie solutions she recommends and the construction details she checks before choosing one.
Minimizer Bras 101
A minimizer does not reduce breast tissue; it changes how the tissue is distributed and how far the bust projects. Tomima explains what minimizers can do, how their construction differs and when she finds them useful.
Top Bra Styles Every Woman Should Own
Tomima has strong opinions about the bras and features that earn a place in a useful lingerie wardrobe. See the styles she considers worth owning and why each solves a different need.
Best Supportive Bras: Seamed Bras
When customers ask Tomima which bras are the most supportive, her answer is seamed cup bras. She shows why seams, woven fabrics and multipart construction can add strength, shaping and support.
Padded Bras vs. Push-Up Bras: What's the Difference?
Padded and push-up bras are often confused, but their padding is placed for different reasons. Tomima shows what separates the two and how the construction changes the result.
Underwire Bras Vs. Wire-Free Bras: Compare and Contrast
Tomima compares the support, shape, coverage, comfort and fit characteristics she sees in underwire and wire-free bras - and why she believes both can have a place in a lingerie wardrobe.
Best Bra Styles For Deflated And Pendulous Breasts
Deflated and pendulous breasts need support, lift, shape, containment and thoughtful breast placement. Tomima demonstrates how she gets this breast tissue into a bra and the features she recommends looking for - and avoiding.
Best Bras For The Plus Size Petite Woman
For a petite, full-busted woman, the right bra size can still be too much bra for a shorter frame. Tomima explains the proportion problems she sees and the specific construction details she recommends checking.
Cleavage Defined: The Hidden Truth
There is more than one kind of cleavage. Tomima explains the difference between separated and touching cleavage, the drawbacks of the touching look, and techniques women can try when that dramatic look is what they want.
Bra Fit Problems & Solutions Videos
Some fit problems become much easier to understand when you can see what the bra is doing. These videos diagnose common problems and show the adjustments, fit checks and bra features Tomima recommends.
How To Minimize Back Fat
Back bulges and bra lines are common concerns, and Tomima has specific construction features she looks for when smoothing them. See how band fit, back design and coverage can change the result.
Why Are My Bra Straps Slipping?
Slipping straps are not always a shoulder problem. Tomima shows how band size, strap placement and bra design can contribute - and why strap adjustment still matters.
How A Bra's Center Panel Should Fit
The center panel can tell you a great deal about fit, but there are legitimate exceptions to the classic tack rule. Tomima shows the standard fit she looks for while HerRoom's current guidance also recognizes close-set or touching breasts, wireless construction, minimizer engineering and individual chest shape.
Why Underwires Can Pop Out Of Your Bra
An underwire that escapes its casing can point to fit, wear, laundering or age. Tomima explains the causes she sees most often and what you can do to reduce the problem.
Why Your Underwire Is Breaking
Broken underwires usually have a reason. Tomima explains how fit, washing, twisting and heat can shorten an underwire's life.
How To Bend Your Underwires For A Better Fit
Underwires are manufactured flat, while bodies are curved. Tomima demonstrates the small bends and adjustments she makes to customize wire shape, improve comfort and help a bra follow the body more naturally.
Bra Construction, Anatomy & Engineering Videos
A bra is an engineered garment. These videos show how seams, wires, foam, fabrics, padding and other construction choices change support, shape, comfort and price.
Best Supportive Bras: Seamed Bras
Tomima explains why she considers seamed cups the most supportive construction and shows how seam direction and multipart cup design influence shape.
Mastering The Cup Size Game
Cup grading is part sizing and part engineering. Watch Tomima demonstrate why the same cup letter changes volume as the band changes.
Why Bras Cost So Much
Bras can contain dozens of components, specialized fabrics and surprisingly complex construction. Tomima compares bras at different price points and explains what she believes you are paying for.
Bra Padding: What Are The 3 Types of Bra Foam Padding?
Traditional foam, memory foam and spacer foam have different properties. Tomima compares the three and explains how their construction affects fit, modesty, breathability and support.
Padded Bras vs. Push-Up Bras: What's the Difference?
See how the amount and placement of padding determine whether a bra is primarily adding modesty and shape or actively pushing breast tissue upward and inward.
Underwire Bras Vs. Wire-Free Bras: Compare and Contrast
The presence or absence of an underwire changes how a bra can be engineered. Tomima compares the structures side by side and explains the tradeoffs she sees.
Sports Bra Fit, Support & Movement Videos
A sports bra has a different job from an everyday bra: controlling breast movement during activity. Tomima explains the design types, features and impact levels she uses when evaluating sports bras, while HerRoom's Bounce Test™ shows selected bras in motion.
Finding The Right Sports Bra
Compression, encapsulation, impact level, straps, closures and fit all affect how a sports bra performs. Tomima explains the differences and the fit checks she recommends before you exercise.
See Sports Bras in Motion: HerRoom's Bounce Test™
Still photography cannot show breast movement. HerRoom's Bounce Test™ videos let you see selected high-impact sports bras while the wearer is moving, adding another piece of information before you choose.

Garters 101
Garter belts and stockings have their own fit, hardware and wearing tricks. Tomima demonstrates how they work and how to put the pieces together.
Best Panty Styles For Your Bottom Type

How To Fit A One-Piece Swimsuit
A one-piece swimsuit must fit through the bust, torso, waist, hips and seat at the same time. Tomima shows the areas she checks before deciding whether the suit fits correctly.
How To Put Panties On The Right Way
Panties can ride, bind or look wrong when they are pulled to a rise they were not designed to have. See how Tomima positions the waistband, seat and leg openings for a better fit.
Shapewear: What Is Light, Firm, Moderate & Extra Firm Control?
Shapewear control levels are not interchangeable. Tomima shows the differences between light, moderate, firm and extra-firm control so you can decide how much shaping you actually want to wear.
