Looking for the best bras for 28C? A UK 28C combines a 28 band with a C cup. Although 28C is stocked by fewer retailers than some more common band sizes, it is available in a range of bra constructions including plunge, T-shirt, padded, balconette, strapless, multiway and non-wired styles.
The best bras for 28C will depend on the coverage, neckline and cup construction you prefer. T-shirt and padded bras provide a shaped cup, while plunge, balconette, strapless and non-wired designs offer different combinations of coverage and construction.
Before buying a 28C bra, it can help to check the equivalent international sizes, nearby sister sizes and visual size comparison. The quick tools on this page show how 28C compares across different sizing systems and related UK bra sizes.

The best bras for 28C are available across several constructions, including padded, wired, plunge, balconette, T-shirt, strapless, multiway and non-wired styles. The most suitable option will depend on the coverage, neckline and cup construction you prefer.
T-shirt and padded bras use shaped or padded cups to create a smoother outline beneath clothing. Both Boux Avenue and M&S offer 28C bras in these types of constructions, although the exact products available can change between collections.
Plunge bras have a lower centre front and are designed to work beneath lower necklines. Boux Avenue currently lists multiple plunge styles in 28C, including padded and T-shirt constructions.
Balconette and demi-cup bras generally have a lower cup line than full-cup styles and leave more of the upper breast uncovered. These constructions are available in 28C from UK retailers, with individual designs varying in padding, wiring and fabric.
Strapless and multiway bras are designed for clothing where standard shoulder straps would be visible. Boux Avenue lists multiway and strapless options within its 28C range, giving another construction to consider for occasionwear or different necklines.
Non-wired bras provide shaping and support without an underwire, using the underband, cup construction and straps instead. Non-wired options are also available in 28C, although the number of styles can vary by retailer and season.
A 28C combines a 28 band with a C cup. Bra cup letters cannot be considered independently from the band because cup volume changes as the band measurement changes.
In the UK cup sequence, this part of the progression runs: AA → A → B → C → D → DD → E. This places C immediately above B and immediately below D.
Remember that bra size combines band size and cup size. A 28C has less overall cup volume than a 34C even though both sizes use the same C cup letter.
The nearest available sister size to 28C is 30B. This size has a similar cup volume but uses a larger band measurement. You can learn more in our Bra Sister Sizes Explained guide .
The appearance of a 28C can vary because breast shape, tissue distribution, torso proportions and bra construction all affect how the same bra size looks.
Because bra sizing combines both band size and cup size, a C cup does not represent one fixed breast volume. For example, a 28C has a smaller overall cup volume than a 34C even though the cup letter is the same.

You can also use the UK Bra Size Visual Comparison Tool to compare 28C with other manufactured UK bra sizes.
Bra size is relative rather than a standalone description of bust size. A 28C combines a 28 band and a C cup, and its overall cup volume differs from C cups on larger bands.
