What Is a Side Support Bra and Is It Worth Trying?
The side support bra is one of the most effective styles available for a fuller bust, and one of the least well known. Most women only come across it when they are fitted properly for the first time, and the reaction is usually the same: why did nobody tell me about this sooner.
If you have ever spent a day in a bra that digs into your shoulders, shifts around by lunchtime, or just does not quite hold things where you want them, you are probably wearing the wrong style, not necessarily the wrong size.
Women in a D cup and above tend to notice the biggest difference, and if there is one brand that has taken this construction seriously, it is Fantasie. They have been making bras since 1901 and the side support bra is arguably what they are best known for.

What is a side support bra?
Most underwired bras do their job through the cups, the wire and the straps. That works fine in a smaller cup, but in a larger one the straps end up carrying more weight than they are built for. Shoulder strain, grooving, that feeling of being pulled forward by the end of the day. It all comes from the same place. And the cup alone cannot always stop a fuller bust from migrating outward and downward as the day goes on.
A side support bra addresses this through construction rather than padding. The side panels are cut and boned to hold the bust from the outer edge, pushing everything inward and forward. The shape you get is rounder and more projected. And because the support comes from the structure rather than the straps, the straps can do less work.
What difference does it make?
For women in a D cup or below, the difference is noticeable but not transformative. For women in a DD cup and above, it can be significant.
The three things most women notice first:
- Shape. The side support construction gives a rounder, more centred shape than a conventional underwired bra. Under fitted clothes, particularly jersey tops, fitted shirts and dresses, this makes a visible difference.
- Comfort through the day. Because the straps are not doing the heavy lifting, they sit on the shoulder rather than biting into it. Women who are used to taking their bra off the moment they get home often find they are much less aware of a side support bra by the end of the day.
- Position. The bust sits where it is supposed to sit, and tends to stay there. In a larger cup size especially, the outward migration that happens in a conventional bra through the day is much reduced.
The Fantasie side support range
Fantasie has built its reputation on making bras for fuller cup sizes that actually work, and side support construction is central to that. The brand's approach is to engineer the bra around the needs of a fuller bust, rather than scaling up a smaller-cup design and hoping for the best.
At Shirley Allum Boutique in Shaftesbury we carry a selection of Fantasie side support bras in sizes from D to K cup. The Pippa is a style worth knowing. It is a full cup side support bra with an underwire, available in a good range of colours and the kind of size range that very few retailers stock properly.
If you are in a D cup or above and have not tried a side support bra, it is one of those things that is easier to demonstrate than describe. Come in and we will show you what we mean.
Is a side support bra right for you?
The style tends to work best for:
Women in a D cup or above. The structural benefit is most pronounced where there is most weight to support. In a smaller cup size a standard underwired bra often does the job just as well. But from D cup upwards, the difference in shape and comfort is significant enough that it is worth trying at least once.
Women with a wider bust root. If your breast tissue extends quite far to the side of your chest, which is common in fuller cup sizes, the side panel helps contain and centre it.
Women with shoulder or neck discomfort from bra straps. If your current bra leaves strap marks or causes shoulder tension, it is worth trying whether redistributing the support load makes a difference. Many women find the strap pressure reduces significantly when they switch to this construction.
Women who want a clean, round shape under clothing. Particularly relevant if you wear a lot of fitted tops, jersey dresses or anything where the shape of your underwear is visible through the fabric.
The Fantasie side support range is available online and in store at Shirley Allum Boutique on the High Street in Shaftesbury. We stock sizes from D to K cup and we are happy to help you find the right style for your shape. If you would like to be professionally fitted before you buy, just come in. No appointment needed, and you can also read our guide on how to find your perfect Fantasie bra.

Frequently asked questions
What is a side support bra?
A side support bra uses structured panels on the outer side of the cup to support the bust from the edge, pushing breast tissue inward and upward. This gives a rounder, more centred shape and reduces the load on the straps, which means less shoulder strain through the day. It is particularly effective for women wearing a D cup and above.
Who should wear a side support bra?
Side support bras work best for women in a D cup or above, women with breast tissue that extends quite far to the side of the chest, and women who experience shoulder strain or strap discomfort with conventional bras. They are also a good choice for anyone who wants a rounder, more projected shape under fitted clothing.
What makes Fantasie side support bras different?
Fantasie has been engineering bras for fuller cup sizes since 1901 and side support construction is central to its design approach. Rather than scaling up a smaller-cup bra, Fantasie builds each style around the specific needs of a fuller bust. The result is a bra that supports from the structure rather than the straps, giving a better shape and more comfort through the day.
Where can I buy Fantasie side support bras in Dorset?
Fantasie side support bras are available at Shirley Allum Boutique on the High Street in Shaftesbury, Dorset. We stock sizes from D to K cup and offer professional bra fittings in store. No appointment is needed. You can also shop the Fantasie range online.
How is a side support bra different from a full cup bra?
A full cup bra supports the bust through the cup and underwire. A side support bra adds structured side panels that support from the outer edge, which gives additional forward projection and reduces the weight carried by the straps. Many side support bras are also full cup in construction, combining both benefits.
