There are four key areas to focus on when shopping for
a new bra. M&S lingerie expert Julia Mercer provides
her step-by-step tips for getting the perfect fit every time.
The underband should be horizontal across your back. It should be snug but with enough room to fit two fingers underneath it.
The wires at the front should sit flat at the breastbone between your breasts.
Your breasts should be fully enclosed in each cup and there should be a smooth line where the cup ends.
The bra straps should be secure, but not tight. If you drop the straps, the bra should stay in the same place.
Looking after your bra will help maintain its fit over time.
