Wacoal Women's Perfect Primer Underwire Bra for Full Figures - Smooth

In this review of the Wacoal Women's Perfect Primer Underwire Bra, the bottom line is simple: it is designed for women seeking reliable, full-coverage support with a smooth silhouette. The bra's biggest draw is its comfortable, two-ply cups and hidden inner sling that combine to shape and support larger busts without excessive bulk. Customers repeatedly praise the fit and softness, and this review focuses on how those construction details translate to everyday wear for fuller figures who want coverage, stability, and straps that stay put.

Key Features

• Two-ply cups: Smooth, double-layer fabric gives full coverage and a clean shape under tops while providing durable support.
• Hidden inner sling: An internal sling creates natural shaping and lifts without needing a visibly structured cup rim.
• Hidden underwire: The underwire is concealed for support with reduced irritation at the wire channel for better comfort.
• Reinforced back and band: An extra layer in the back and band adds stability and improved support for larger sizes.
• Kicked-in back straps: Straps are angled to minimize slipping and are stretch-comfort with full adjustability for a secure fit.

Who It's For

This bra is best for women who wear fuller cup sizes up to a G cup and want full-coverage everyday support that smooths under clothing. It suits those who prioritize comfort and a reliable fit over decorative or sheer styling, and who need a bra that offers wide support across the back and under the arms.

Shoppers who prefer unlined, breathable sheer fabrics or very fashion-forward bralettes should look elsewhere, as this style emphasizes structure and coverage rather than delicate lace or minimal coverage options.

Pros & Cons

Pros

• Comfortable, soft two-ply cups that customers say feel smooth against the skin.
• Strong support and shaping from the hidden inner sling and underwire without feeling bulky.
• Wide band and reinforced back provide added stability for larger sizes.
• Straps stay in place thanks to the kicked-in design and are fully adjustable for a personalized fit.

Cons

• The focus on coverage and structure means it is not a sheer or fashion-forward option for those seeking minimal look.
• Built for fuller figures up to G cup, so it may be more supportive than necessary for very small-busted wearers.
