Size 34HH Bikinis

Construction Features That Matter Most at 34HH

At 34HH, internal construction is what separates a bikini top that works from one that looks good on a hanger and fails in the water. Boning is the first thing to look for — vertical boning along the sides of each cup prevents the fabric from collapsing inward under the weight of a very full bust, maintaining shape and projection throughout wear. Underwire at this size should be rigid rather than flexible, with a deep cradle that supports from underneath rather than just framing the front of the cup. The channeling that holds the underwire in place matters too — reinforced channeling prevents the wire from twisting or migrating, which becomes a real issue at higher cup volumes. Look for cups lined with a support layer beneath the outer fabric rather than relying on foam padding alone; foam compresses in water and loses its shape, while structured lining holds its form. Wide elastic along the underband — at least an inch — gives the band enough surface area to anchor without digging. And check the strap attachment points: straps that attach to reinforced panels rather than directly to the cup fabric distribute tension far more evenly at 34HH.

Cup-Sized Bikinis, Curated by Fit Experts

At The Bra Diva, we carry bikinis the same way we carry bras — by actual bra size, not just by small, medium, or large. Every style in this collection is selected for its construction quality, true-to-size fit, and ability to hold up in and out of the water. Our team has been fitting customers since 1987 at our Cherry Hill, NJ boutique, and we bring that same expertise to every size we carry online.
