Sexy Lingerie Styles: Sets, Bodysuits & Costumes

Lingerie sets

A matching lingerie set is a cracking place to start when you want a complete bedroom look without playing mix-and-match. Pick the coverage and details that take your fancy, whether that's a cheeky two-piece or a top and skirt. Check the listing for what's included; stockings and styled accessories may be separate.

Bodysuits & one-piece lingerie

Want an outfit that makes an entrance? A lingerie bodysuit joins the top and knickers in one piece, with necklines, open backs and leg cuts that show off different parts of your body. Have a look at the fastenings and strap details too. A daring design is even better when it sits comfortably and lets you move.

Mini dresses & cut-out styles

A revealing mini dress is a cheeky choice when you fancy keeping something on. Mesh, open-weave fabrics and cut-out designs offer different levels of coverage, from a teasing glimpse to a much bolder look. Compare the length, stretch and where the cut-outs sit so you know just how daring your outfit will be.

Adult costumes & dress-ups

Got a dress-up fantasy you've been meaning to try? An adult costume can give your usual night in a properly cheeky twist. Choose a character or look you're keen on, then check whether you're buying the whole outfit or a single piece. Planning some role-play together? Pick a scenario you're both excited about and agree on what you're comfortable with.

Lingerie sizing advice

How to Choose Your Lingerie Size

Measure your bust, waist and hips, then compare them with the size chart for the specific garment. Your usual Australian clothing size is a starting point, but sizing varies between brands and styles.

One size doesn't mean every size. It describes a stated size or measurement range, often in a stretchy design. Check that range and any cup or support information before ordering. If you're between sizes, ask us about the item rather than assuming the fabric will stretch enough.

Lingerie Gifts & Kinky Date-Night Ideas

Buying lingerie for your partner? Go for something they'd love to wear, not just something you'd love to see. Take a hint from their favourite colours and styles, and ask about sizing. Browsing together can be half the fun, and saves you guessing their measurements.

Fancy adding a kinky twist to date night? Pair your outfit with an adult game, or browse bondage accessories for an idea you're both up for. Have a chat about what sounds fun and what doesn't before you get started.

Your order comes in plain, discreet packaging. See our delivery information for destinations, costs and estimated timeframes, and check the returns policy before buying intimate garments.

Sexy Lingerie FAQs

What lingerie should I choose for the first time?

Start with a style you already like, then go a little cheekier if you fancy it. A matching set is easy to build an outfit around, while a bodysuit gives you a complete look in one piece. Check the fabric and measurements, and choose how much you want to show. Sexy doesn't have to mean barely there.

How do I choose the right lingerie size?

Use your bust, waist and hip measurements with the brand's chart for that product. Letter sizes such as S/M and M/L aren't identical across brands. Where a listing doesn't give enough detail, use “Chat with us” before ordering. Our lingerie buying guide is a useful place to start.

Will one-size lingerie fit me?

Only if your measurements fall within the range given for that garment. Stretch, strap adjustment and the design all affect fit. One size isn't a guarantee of fit, and a stretchy garment may not provide the same bust support as a structured bra.

Are stockings and accessories included?

Not always. Read the product's included-pieces list rather than relying on the styled photo. Some listings are a single skirt, top or bodysuit; others are multi-piece sets. Ask us to clarify anything that isn't listed.

What does crotchless lingerie mean?

Crotchless lingerie has an opening at the crotch. This makes it a cheekier option for a bedroom outfit. The opening's size and position vary between designs, so check the photos and description rather than assuming every style is the same. The rest of the garment still needs to fit comfortably.

How should I wash and store lingerie?

Follow the garment's care label first. If hand washing is recommended, use a mild detergent and handle lace, mesh and trims gently. Avoid tumble drying unless the label allows it. Let pieces dry completely before storing them away from rough fastenings that could snag delicate fabric.

Is lingerie sent in discreet packaging?

Yes. Orders come in plain, unmarked packaging. For delivery options and estimated timeframes, read our shipping and discreet delivery information.

Can I return lingerie if it isn't right?

Check our returns and refunds policy before ordering, including the conditions for intimate items. If you're unsure about a particular garment, contact us before trying it on or removing tags or seals.
