"Choosing lingerie is incredibly personal, as every woman's shape—as well as her size—is unique, which is why style, comfort and flattering fit are key," explains Julia Mercer, head of specialist services at Marks and Spencer. “I would usually recommend a T-shirt bra for women with a smaller bust, whether that’s wired or non-wired. This style will not only offer comfort and support but will also give a great shape and silhouette under any outfit.
"Bralettes are also a really great option. With a more relaxed and casual attitude to dressing and emphasis on comfort, we know our customers are looking to underwear which creates a softer, more natural silhouette. It's also important to get the right size. M&S offers a free bra fitting service in our stores, with our experts on hand to help you find the perfect fit."
Here are some of Mercer's top tips for checking you have the perfect bra:
1. Underband: This should be parallel to the floor and secure enough that only two fingers can fit under the elastic.
2. Centre front: Make sure this sits completely flat against the sternum.
3. Side wire: This should be flat against the ribcage and never digging into the breast tissue.
4. Cup capacity: The breasts should sit fully into the cup without any spillage.
5. Straps: These should be adjusted to just fit two fingers on top of each other, which will give the right pressure for your shoulder.
