Push-up bras usually want something back: a strap you keep hauling up, a wire that announces itself by mid-afternoon, a shape that reads as padded from across the room. The Constant plunge asks for the least of anything in this guide. The front dips low enough to vanish under a V-neck or a wrap top, and the padding is shaped to lift rather than to build a shelf.
We wore it through desk days and dinners out, and what stood out was the lack of maintenance. The band stayed level, the cups stayed put when we stood up, and the straps held their adjustment. There is enough strap length to cross them in back when a racerback top calls for it, and the cups are smooth enough to disappear under a thin knit.
Fit is the reason it takes the top spot. Of the plunge and lace styles here, this is the one whose band and cup most reliably matched its label — the difference between ordering online with confidence and ordering two sizes to try. If you are between cups, go up: the cups run small on some bands. Don't expect drama either. This is lift and shape rather than a two-cup special effect; the Wingslove below is the better call for that.
Bottom line: We recommend the Constant plunge as the push-up to buy first: it lifts enough to change how a V-neck sits, fits true enough to order without a fitting room, and never looks padded.
