## Checking Underwire Fit The underwire of the 75345 should rest flat against the ribcage, fully encircling the breast tissue without sitting on it or poking into the armpit. The center gore (the fabric between the cups) must lie flush against the sternum. If the wires dig into breast tissue, the cups are too small. If the wires float away from the body or the gore lifts, the cups may be too large or the band too loose. The underwire should follow the natural crease under each breast without extending too far back or forward. ## Evaluating Band and Strap Fit The band should sit level around the body and feel snug on the loosest hook when new, allowing room to tighten as the elastic relaxes over time. You should be able to slide two fingers underneath comfortably. If the band rides up in the back, go down a band size and up a cup size. Straps should stay in place without digging into the shoulders. Adjust them so they provide light lift but do not carry the main support load. For the 75345 underwire design, properly adjusted straps help keep the cups positioned correctly throughout the day. ## Assessing Cup Fit Cups should fully contain the breast tissue with no spillage over the top, sides, or under the wire. There should be no gaping at the top edge or wrinkling of fabric. Soft tissue should sit smoothly inside the cup without creating a double-bust appearance. Move your arms and bend slightly to test whether the breasts stay centered. If tissue escapes during movement, try a larger cup or a style with more side support. The Vanity Fair 75345 underwire construction aims for secure containment, so cups that allow shifting indicate an incorrect size. ## Common Fit Problems and Adjustments A band that feels too tight may require going up one band size while dropping one cup size. Cups that wrinkle usually mean the cup is too large, so decrease the cup letter. If the underwire presses uncomfortably, confirm that the band is not too small and that the cups fully enclose the tissue. Straps that slip often signal a band that is too loose. Always re-measure after major weight changes, pregnancy, or hormonal shifts, as breast shape and size can vary. When trying the 75345, wear it for a short period at home to check all-day comfort before deciding.
## Additional Fit Tips for Underwire Styles Wash the bra according to care instructions to maintain elasticity and shape. Rotate multiple bras so the elastic recovers between wears. Position the underwire carefully when putting the bra on: lean forward slightly, scoop breast tissue fully into the cups, then fasten and adjust. Check the fit in a mirror from multiple angles. If the calculated size does not feel right, test one size up and one size down in both band and cup to locate the best match. Consistent measuring technique yields more reliable results than relying on previous sizes alone. Accurate measurements combined with careful try-on evaluation produce the most comfortable and supportive fit for the Vanity Fair 75345 underwire bra.
