Commercial bra cups often lack the depth or shape needed for a large bust. You can create your own for use in sundresses, corsets, or evening wear.

For costume enthusiasts, standard foam patterns often don't provide the necessary curvature for a larger bust.

You can use hooks to strap foam breastplates directly onto a supportive bra to keep the armor from shifting during wear. 4. Quick Fixes: Modesty & Fit

Commercial sewing patterns often don't account for "sufficient boobage," leading to bodices that are too short in the front.

For dress bodices, consider adding a half-inch to an inch of extra seam allowance to the front length to ensure the waistline sits correctly below the bust rather than riding up. 3. DIY Breastplates for Cosplay

Start with measurements from the shoulder to the bust point, the bust to the underbust, and half the nipple-to-nipple distance.

To stop the band from rolling up under the bust, use 5/8-inch strap elastic (which has a plush side and no decorative edge) instead of standard picot elastic. 2. Tailoring & Pattern Adjustments

Use fusible fleece or laminated bra foam for a steady, strong structure. For extra stability, double up on layers of firm powernet for the bra band.
