How to take your measurements

1

Measure your underbust

Place the tape directly under your bust. Measure close to your body, without leaving a gap and without hindering your breathing.

2

Measure your bust

Place the tape around the fullest part of your bust, generally at the height of the nipples.

3

Measure your waist

Measure horizontally around the narrowest part of your natural waist, without pulling in your stomach.

4

Measure your hips

Place the tape around the fullest part of your hips and buttocks.

Tip: take your measurements while wearing a comfortable, non-padded bra. Measurements are a starting point, and fit may vary depending on the cut.

Determine your cup size

Subtract your underbust measurement from your bust measurement, then use the resulting difference.

Good to know: Ulla uses the European cup progression and does not offer a J cup. The sequence goes directly from an I cup to a K cup.

Choosing by product type

Underwired bra

The underwire should fully surround the bust and rest against the body without compressing breast tissue.

Non-wired bra

The underbust band should provide stable support while remaining horizontal and comfortable.

Sports bra

Choose your usual size and ensure the bust remains stable without excessive compression during movement.

Molded bra

The cup should completely envelope the bust without any gaps, spillage, or wrinkling.

Bodysuit

Use your back size, cup, waist, and hip measurements to achieve a balanced fit.

Briefs or shapewear

Choose based on your waist and hip measurements. The material should smooth the silhouette without hindering breathing.

How to recognize a good fit

The back band

It must remain horizontal and provide the bulk of the support without riding up the back.

The cups

The bust should be fully enclosed, with no spillage, gaps, or compression.

The straps

They should remain comfortable without slipping or leaving deep marks on the shoulders.

The bridge

On an underwired bra, the bridge should rest against the sternum without pressing on the bust.
