Everyday Bras, Seamless Underwear & Smoothing Layers: Comfort Basics Under Outfits

Purple Star emoji 18 items
Out of roughly forty bras, bodysuits and pairs of underwear considered for this list, anything that dug in, rolled up or showed through a tee got cut, and so did anything that needed hand-washing every week. What is left is the under-layer lineup tha...

This is the bra I point friends to when they want something that looks like skin under a fitted tee. The wide side wings smooth the band area, and the stretch fabric forgives sizes in between. It runs from AA cups up to a 46 band, which is a lot wide...

Aerie turned its bestselling bralette fabric into a bodysuit, and the buttery stretch means no hooks and no hem riding up at the waist. I tuck it under jeans or a blazer and forget it is there. Light support only, so it suits a lower-impact day rathe...
Aerie SMOOTHEZ Bra-ish Bodysuit

One size covers a range from 4 to 14, so I never worry about ordering the wrong number, and the lace lies flat under trousers. It has been around since 1986 for a reason. Pricey at about $24 a pair, so I buy one color at a time and rotate.
Hanky Panky Signature Lace Original Rise Thong

A built-in-bra cami is the fastest layer under a cardigan or button-down, and this AIRism fabric stays cool and slick instead of clinging. The hem is finished instead of elastic, so there is no line at the waist. At about $30 it is the cheapest smoot...
UNIQLO AIRism Bra Camisole

Laser-cut edges and heat-sealed labels mean no tag scratch and no ridge under leggings or thin knit pants. The fabric is ultra-smooth microfiber, and the hipster cut gives full rear coverage that stays put. Multi-packs are cheaper per pair, so stock ...

The memory foam cups mold to your shape, and the smoothing sides keep the bra from wrinkling visibly through a tee. ThirdLove is the only brand I know that sells half cup sizes, which is a big help if you are always in-between. The price is around $7...

This is a regular layering tank, not a shapewear piece, and that is exactly why I wear it: the TENCEL Modal feels like nothing on, and the scoop neck sits low enough to wear under a V-neck sweater. It is machine washable, and ivory holds up under whi...
Eberjey Gisele TENCEL Modal Everyday Tank

Built to be undetectable under leggings, with a snug tight knit that does not slip or ride up during the day. It has a cotton gusset, which most seamless thongs skip. Reviews on this style are mixed, so check your size chart and start with a single p...
lululemon InvisiWear Mid-Rise Thong Underwear

Strong compression that smooths the thigh and tummy line under a slip dress or fitted skirt. It is strong compression, so I wear it for a few hours at a party or event rather than a full day. Pair it with the lightest bra on this list so nothing adds...
SKIMS Seamless Sculpt Mid Thigh Short

The microthin spacer fabric in the back smooths bulges that show through knit tops and bodycon dresses. Hidden sling cups add support, and the extra side and back coverage sets this apart from a basic t-shirt bra. Best for days when a fitted top will...
Wacoal Back Appeal Underwire Bra

A wire-free bralette with a scoop neck and slim adjustable straps in a fabric that feels like a second skin. The tonal logo band is subtle enough to peek out of a V-neck without looking loud. It sells for around $46 but frequently goes on sale.
Calvin Klein Form to Body Lightly Lined Bralette

A peach-fuzz soft layer that works as a top, a base layer under a blazer, or a smooth foundation under a wrap dress. The fabric is lightweight and stretchy. This is a layer to wear as an outfit by itself, not as a hidden under-piece.
lululemon Wundermost Ultra-Soft Nulu Square-Neck Long-Sleeve Bodysuit

I keep a few of these for heavy days and travel. They are thin enough to disappear under leggings, with bonded edges that do not leave lines. The absorbency is roughly six super tampons, which means a single pair can replace a pad in a pinch.
Knix Super Leakproof No-Show Bikini

There are no hooks to dig in, and the power mesh from the cups to the shoulders keeps side spill under control. The AIRism fabric is quick-drying, so it handles hot days better than cotton does. Sizes run XS to XL, so try it on first if you are betwe...
UNIQLO Wireless Bra

My pick for strapless dresses and off-the-shoulder tops, because it smooths from bust to thigh without any straps showing. It is strong compression, so I treat it as an occasion piece and not an everyday one. Size down only if you want maximum hold.
SKIMS Seamless Sculpt Strapless Shortie Bodysuit

The cheeky cut is a good middle ground when thongs feel like too little and briefs feel like too much. The fabric is light and smooth, with no seams to show under tight pants. It is also cheap enough to buy a few colors.
Aerie SMOOTHEZ No Show Cheeky Underwear

Full-coverage boy shorts that stay put under dresses and skirts, with a high waist that does not squeeze. It is the one I choose when I want zero chafing on thighs in warm weather. At around $20, it also goes on a 3-for-$39 deal.
SKIMS Fits Everybody Boy Short

A soft cotton hipster for days when you want breathability without the visible lines of regular cotton underwear. It sits just below the waist for low-rise pants. I wear these for travel days and workouts, then switch to microfiber for fitted outfits...
