Learn how to choose between underwired and non-wired bras with a practical fit guide. We compare DIM Generous and DIM Icons to help you decide.
Quick answer
Choose an underwired bra when you want precise support and a defined shape, and a non-wired bra when you prioritize light comfort and an athletic feel. DIM Generous is underwired for structure, while DIM Icons is non-wired for softness.
How underwired and non-wired bras differ in support and shape
Underwired bras use curved wires to anchor the cups and lift the bust, which creates a more defined silhouette. Non-wired bras rely on fabric construction and band tension for support, so they feel softer and less rigid. The trade-off is that non-wired styles may offer less shaping, while underwired styles can feel firmer against the ribcage.
When to choose each style for daily wear
For long days at a desk or light activity, a non-wired bra like DIM Icons in white cotton modal can feel airy and discreet under light clothing. For occasions when you want a rounded shape and reliable hold, an underwired option such as DIM Generous in raspberry microfibre and tulle provides a more structured fit. Consider your outfit and planned activity before deciding.
Fit checks that apply to both styles
Regardless of wire preference, the band should sit level and snug without digging, and the center gore should rest close to the sternum. Cups should contain the whole breast without spillage or gaping. Always try bras on with the band fastened on the loosest hook to allow for future adjustment.
Steps to choose your DIM bra fit
- Measure your underbust and bust: Use a soft tape measure to find your underbust and full bust measurements. Subtract underbust from bust to estimate your cup size. Common mistake: measuring over clothes or pulling the tape too tight. Write down both measurements and recheck them once.
- Decide on wire preference based on activity: If you want shaping and lift for work or events, lean toward underwired. If you prefer a relaxed feel for lounging or light exercise, choose non-wired. Checkpoint: consider whether you will be sitting or moving a lot. Match the bra to your main activity for the day.
- Try on with the band on the loosest hook: Fasten the bra on the loosest hook and adjust straps so they lie flat without digging. The band should feel snug but not tight. Mistake: starting on the tightest hook, which leaves no room for adjustment. The band provides most of the support, so prioritize its fit.
- Check cup coverage and gore position: Lean forward and scoop your breast tissue into the cups. The center gore should sit close to your body, and the cups should fully contain your breasts without spillage or gaping. Checkpoint: if the gore floats or cups wrinkle, try a different size. A flat gore and smooth cup edge indicate a good fit.
- Move around to test comfort: Raise your arms, twist your torso, and sit down to see if the bra stays in place. Wires should not poke, and the band should not ride up. Mistake: judging fit only while standing still. If the bra shifts or digs during movement, adjust size or style.
