Unless you're wearing gauzy fabrics in November, no one's going to know what bold color or pattern you've got on under your winter knits. So why not mix in some cute feminine florals just for kicks? (Warning: This is how lingerie obsessions get started.)

Keen to look one size smaller in a brassiere that doesn't resemble your grandmother's foundation garment? Attractive minimizers do exist, like this lace version (with a low neckline and sufficiently wide straps) that goes up to a G cup.

Instead of your DIY efforts with a safety pin, might we suggest springing for one of these supremely useful styles? The Y-back with molded cups and "sueded" mesh sides is soft and supportive, while the lace version is as gorgeous as it is invisible under shoulder-baring dresses.

• Two words: spacer fabrics. Minuscule air pockets worked into these "3-D" textiles make traditional contouring bras super-lightweight. Just be prepared to look your actual size (without the hefty padding) on the days you wear a T.

If somewhere along the line your pretty little things gave way to well-made shapers and ho-hum underwires, it could be time to bring some femininity back. Unlined lace will give you that sheer, so French effect; a wireless pima cotton version is equally fetching (and comfy too).

If your cup runneth over, let it (a little). This demi style from Passionata, a newly relaunched European line that was popular in the '80s, goes up to a G cup. And with a lovely yet substantial layer of tulle in front, it offers support as well as some tasteful peekaboo action.

Practicing years of devotion to a single go-to can be limiting. For an update, check out Calvin Klein's relaunched Perfectly Fit line. Crafted for "extreme comfort" with bonded wings, velvet flocking, and thin memory foam, the range of styles offers T-shirt-to-office-ready options in cool shades.

Do smaller chests need the extra support? Not exactly. But an underwire can still give you a little push-up effect. Combine this feature with a sexy demi shape in mesh or floral lace and you've just found the A team's new fave.

IF age or breast-feeding has left you less, shall we say, well-rounded, this bra will more than mind the gap(s). Instead of providing a simple push-up, it's padded at the top to fill in what's turned more concave. It comes in 27 sizes and neutral hues as well as this icy blue.

Just because there are carousels full of them at your nearest big-box store doesn't mean you have to buy a run-of-the-mill all-white brassiere. Treat yourself—sophisticated styles for larger sizes are available in flattering, fashionable shades like burgundy, forest, or plum. Some of these alluring date-night numbers go up to a size N.

If you're wearing an underwire more by default than design, you might want to put some supportive but less rigid options into rotation. Spanx's bralette holds you in with four rows of hook-and-eye closures and is front-lined for extra coverage. Anita's wire-free version is so comfortable, it is recommended as a post-surgery bra. (It also has pockets for prostheses.)

• Individual cups shouldn't be too much to ask for when you're exercising. If you're larger, this wired option by Panache features bra sizing up to a 40H. Nike's Pro Rival style (available in 25 sizes) is similarly designed to showcase your shape while providing enough compression to be called its "highest level of support."

It's no big deal to fling off your bra once you've walked in the house, but sometimes you don't want to be surprised by visitors and have to answer the door sans support. Enter the Genie, which one of our fashion editors describes as "like a Snuggie for your breasts," and more of a "downtime bra." To wear in privacy, or even to bed, this may be the world's most comfortable seamless stretch-cotton bra.
