No lace. No logos. Just cool.
Some lingerie is meant to be seen. Some is meant to be felt. The Insider collection? It’s meant to do both, without anyone knowing it’s there.
Inspired by the sleek sex appeal of ’90s supermodels strutting through SoHo and the effortless polish of New York’s model-off-duty scene, Insider is Skarlett Blue stripped down to the essentials. No lace. No frills. Just smooth, ultra-stretch styles that move with you from Chelsea art strolls to late-night cab rides.
What is Insider? Think seamless bras that disappear under tightest tees, G-string underwear that works under literally anything, and bodysuits so versatile you’ll be styling them three ways before lunchtime.
The Best Convertible T-Shirt Bra That Takes You from a SoHo Coffee Run to a Midtown Meeting
Your search for the best t-shirt bra ends here. The Insider Convertible T-Shirt Bra is the definition of an everyday bra: seamless, smooth, and ready for whatever New York throws at you. Designed to move with you (and we mean really move), it’s made from ultra-stretch matte jersey with flex-fit foam cups that mold to your body.
Why we love it:
- Lightly lined for a natural shape without bulk
- Convertible straps so you can wear it classic or x-back
- Soft, 4-way stretch matte jersey that feels like second skin
- Smooth cups = invisible under even the tightest tees
- The perfect nude t-shirt bra option for lighter fabrics
Pair it with a fitted tee and tailored blazer for work, a vintage shirt for brunch in Nolita, or that silk cami you’ve been saving for a rooftop nightcap.
The Seamless Underwire Bra for Brooklyn Flea Market Weekends
The Insider Seamless Underwire Bra is what happens when you take all the lift and support of a classic bra and give it a modern, minimalist makeover. It’s the kind of bra you forget you’re wearing until someone asks you where you got it.
Why we're obsessed:
- Seamless underwire cups that disappear under knits
- A fit that stays put from subway sprints to happy hour
- Sculpted shaping without stiff padding
- Low cut neckline perfect for V-neck dresses
- Perfect as a comfortable everyday bra
Whether you’re styling a crisp white button-up or a slinky tank, this seamless underwire bra keeps you looking smooth, lifted, and totally distraction-free.
The G-String Thong for Casual Lower East Side Walks
When your outfit calls for zero lines and maximum confidence, reach for the Insider Seamless G-String Thong. It’s G-string underwear done the Skarlett Blue way: sleek, soft, and so comfortable you’ll forget it’s there.
Why it’s the best seamless thong for tight outfits:
- Laser-cut edges for a completely invisible fit
- Ultra-soft stretch fabric that moves with you
- Minimal coverage with a flattering high-cut leg
- Available in your favorite neutrals
Whether it’s leggings for your 8 a.m. yoga class or your favorite slip dress, this seamless G-string thong has you covered (well… barely).
