Compare Wacoal's Perfect Primer Push Up Bra and Self Assured Push Up Strapless Bra to find the right lift for your outfit and comfort needs.
Quick answer
Choose Wacoal's Perfect Primer Push Up Bra for everyday lift under tops and dresses, or the Self Assured Push Up Strapless Bra for strapless and low-cut styles that still need cleavage enhancement.
Lift vs. versatility: the core trade-off
A standard push up bra gives you consistent lift with straps that keep the cups in place. A strapless push up bra must balance the same push-up power with grip and structure so it stays up without straps. That engineering difference affects how each bra fits and feels.
The Perfect Primer Push Up Bra uses graduated foam cups to create a natural boost, while the Self Assured Push Up Strapless Bra combines push-up padding with a plunge neckline and a strapless design. The trade-off is simplicity versus adaptability: the Perfect Primer is easier to wear day-to-day, but the Self Assured handles a wider range of necklines.
How to decide between them
- Everyday lift under tops: The Perfect Primer Push Up Bra is your go-to for t-shirts, sweaters, and button-downs. Its soft fabric and graduated cups give a gentle boost without adding bulk. You can wear it all day without thinking about it.
- Strapless or low-cut outfits: The Self Assured Push Up Strapless Bra is built for off-shoulder tops, halter dresses, and plunge necklines. It stays in place while still providing push-up shape, so you don't have to sacrifice lift for a bare shoulder look. If you wear strapless styles more than once a month, the Self Assured is worth the investment.
- Comfort vs. security: The Perfect Primer's straps help distribute weight evenly, making it more comfortable for long wear. The Self Assured relies on a grippy band and internal structure to stay up, which can feel snugger. Try both to see which fit you prefer.
