Between Sizes? Here Is What to Do

Falling between two sizes is completely normal and nothing to worry about. With a few simple principles, you can choose confidently and end up with a piece that fits as if it were made for you.

Decide on the fit you want

Do you prefer a snug, second-skin feel or a relaxed, comfortable one? Size down for the former and up for the latter. There is no wrong answer, only your preference.

Let the most important measurement lead

For tops, prioritise the underbust and bust. For bottoms, prioritise the hips. Choose the size that comfortably fits your largest relevant measurement.

Use adjustable styles

Tie sides, halter necks and adjustable straps are your best friends when you are between sizes, letting you fine-tune the fit exactly to your body.

And remember, separates mean you never have to compromise: order one size on top and another on the bottom whenever you need to.
