20 Red Lingerie Sets Under $100 That'll Make You Swoon

There’s a reason why halter bralettes have been popping up all over your favorite fashion bloggers’ feeds these days. The beauty of one of these lacy numbers is that you can easily layer them under an off-the-shoulder top or sweater because the ornate straps are meant to be shown off. This one is lined and lightly padded, and you can easily remove the inserts — or keep them in for a little extra cleavage boost. Try it under a racerback black dress — that little pop of red is bound to turn heads. Did I mention the matching low-rise thong, which never goes out of style?

Balconette bras are one of the best lingerie inventions to date. Not only do they put your cleavage prominently on display, but they also lend just enough lift and shaping. That means they’re the perfect choice when you’re looking for less coverage than a standard T-shirt bra, but also less drama than a push-up bra. This one is brimming with accents, like tiny ribbon bows and scalloped trim. Pair it with the corresponding lace shorts if you’re feeling cheeky, or the lace thong if you want to show off more of your derriere.

What sets this set apart is the unique bra design — with a flirty keyhole in the front and bow knot in the back, it’s the perfect blend of sweet and seductive. This set is also ideal if you’re looking for a tad extra coverage on the bottom but also want to accentuate those curves. Heads up — you’ll no doubt be feeling like a full-on ‘40s Hollywood starlet in the retro-inspired high-waist panty.

This allover lace set is actually super versatile — it’s comfy enough to lounge around in at home on a lazy Sunday, but also cute enough to surprise your partner with on date night. Delectable ribbon bows on the bralette lend a certain sweetness to the set, while the lace cheeky bottoms amp up the sex appeal.

Seeking to show as much skin as possible? This set leaves hardly anything to the imagination, thanks to cutouts on cutouts. The floral detailing on the bra lends an elegant edge, while the super strappy bottom is bold — with subtle bondage vibes.

Who says a lingerie set has to consist of a bra and panty? This babydoll set offers slightly more coverage, while still showing off those legs — and that fabulous cleavage. Artful cutouts show off the stunning floral lace bralette, and the sheer fabric provides a peek at the cute matching thong.

There are lots to love about longline bras. The extra fabric beneath the cups offers a little extra support for the gals (which comes in handy if you’re full-busted), and it also lends a little shaping around the upper torso as well. This bra features a plunging neckline, making it an ideal companion for low-cut dresses and tops.

I definitely did a double-take when I saw the price point on this one. The delicate lace, eye-catching halter bra design, and breathtaking shade of burgundy make a super affordable set look surprisingly luxe.

Sometimes, simplicity is sexy. If you’re looking for some red underthings without all the bells and whistles, look no further than this sheer set, which will disappear under any ensemble thanks to the absence of accents. The unlined bra offers lightweight support without adding volume, and the see-through low-rise bikini panty is just as comfy as it is cute.

Can you say criss-cross? The plethora of strappy details on this sultry set lends an extra dose of attitude, as does the attention-grabbing keyhole at the bottom of the bralette. The highlight, however, has to be the subtle ruching on the backside of the panty, which is bound to make any booty look poppin’.

You can’t go wrong with a push-up bra if you’re aiming to accentuate your cleavage. Not only does this one lift your bust, but the multi-part cups also help to gently shape it as well. Plus, this neutral shade of cranberry can complement anyone. Just be sure to go up a size if you’re a C or D cup, as the retailer recommends.

What makes this striking set stand out is definitely the high-waist panty, making it the perfect choice when you want to flaunt. As a bonus, the corset-inspired tie-up detail on the back of the panty adds a bit of visual intrigue.

Channel your inner bombshell in this sassy little set, which includes a bustier with a lace bodice and a matching G-string panty. (Note: the thigh-high stockings are sold separately.) With molded underwire cups and a long hook and eye back closure, the bustier is actually incredibly supportive — and since the adjustable spaghetti straps are removable, you can easily convert it to a strapless style.

There’s something about this sweet little three-piece set — maybe it’s the innocent-looking shortie with the ruffle hem and the girlish bandeau or the all-over heart print. Either way, this sheer lingerie can double as loungewear, and since it’s super lightweight, it’s an ideal pick for those sweltering summer nights. When you're feeling saucy, you can take off the shortie and just wear the itty bitty G-string underneath.

This three-piece option not only includes a sexy semi-sheer chemise and matching panty, but also a luxurious lace-trimmed robe, making it the perfect set for an impromptu striptease. You can achieve a variety of looks with this set, too — mix and match the robe with other lingerie sets, skip it altogether and just rock the chemise, or just wear the robe and panty for a racy combo.

Perhaps the most unique and eye-catching detail of this glamorous set is the skirted panty, which offers a bit of coverage in the back and a flirty peek-a-boo window in the front. Note that you can easily achieve a flawless fit with the longline bralette, as it includes a row of several hook-and-eye closures in the back, as well as adjustable straps.

You guys — ICYMI, the ‘90s are back, which means chokers and crop tops are legit everywhere. That’s just one reason to scoop up this long-sleeved set, which features a see-through top with heart-shaped embroidery and a coordinating cheeky boyshorts. Bonus: The T-strap choker is removable, so you also have the option of wearing the top as a simple V-neck, too.

I’m a firm believer that a teddy is a lingerie staple because it looks phenomenal on any body type. This burgundy stunner has a built-in balconette bra with wide straps for maximum lift, support, and shaping around the bustline. The simple G-string panty allows the teddy to steal the spotlight — and that it does, with romantic lace cups and side panels as well as dainty bottom ruffles. Side note: This same set also comes in a large range of sizes.

Show a little shoulder in this three-quarter-sleeve set, which includes a see-through lace crop top and a sassy tanga panty. Feeling daring? You can totally wear this top out with a pair of high-waisted black jeans or denim shorts by simply layering a solid bandeau underneath it.
