The easiest way to make a tank top and underwear look like a set is to repeat one thing between them: the colour, the fabric or the finish. Pick a fitted tank, pair it with briefs or trunks in the same colour family, keep the fabrics in the same "weight class", and you have a coordinated base layer without buying a matching set.
Why coordinate your tank and underwear at all?
Most men treat the tank top and the underwear as two separate decisions. That works until the moment both are on show: changing at the gym, a hotel room, a lazy Sunday at home, or a night when the shirt comes off. A coordinated pair simply looks intentional.
- It looks finished. Two pieces that relate to each other read as an outfit rather than leftovers.
- It simplifies the morning. If tanks and underwear share a small colour palette, almost any combination in the drawer works.
- It suits the slim, fitted cuts. Close-fitting tanks and low-rise briefs follow the same body lines, so they naturally look like a pair.
Three ways to build a matching look
You don't need identical pieces. Choose one of these approaches and stick to it.
1. Same colour, head to toe
Black tank, black briefs. White tank, white trunks. It is the cleanest, most "set-like" option and it works in every country and every season. Black is forgiving; white looks crisp but shows wear sooner, so keep white pairs for when they are fresh.
2. Neutral top, colour below
A black or white tank on top, and a single colour underneath, such as green, red or blue. The tank acts as a frame and the underwear carries the personality. This is the most flexible approach if you already own a few plain tanks.
3. Same fabric family
Match the texture rather than the colour: an open mesh tank with mesh briefs, or a smooth, silky vest with ice silk trunks. Even in different colours, matching textures make the two pieces look related.
Match the fabric, not just the colour
The quickest way to spoil a matching look is mixing fabrics that feel and look worlds apart. Use this as a rough guide.
| Tank top | Pairs well with | Best moment |
|---|---|---|
| Mesh slim fit muscle tank | Mesh briefs, low-rise briefs | Warm rooms, nights out, holidays |
| Shape up muscle tank | Low-rise briefs, trunks | Under a shirt or tee, gym changing room |
| Ice silky vest | Ice silk trunks | Office days, travel, lounging |
The Ice Silk Trunks are made from soft modal with mesh panels for airflow, which sits nicely next to the smooth, silky material of the Ice Silky Vest. The Mesh Slim Fit Muscle Tank uses a highly elastic, breathable material, so it looks right next to the stretchy, airy mesh of the Breathable Mesh Underwear.
Colour combinations that work
Our tanks come in a deliberately short list of colours: the Mesh Slim Fit Muscle Tank in Black, Deep Blue and White, the Shape Up Muscle Tank and the Ice Silky Vest in Black and White. That makes the underwear the place to play.
- All black: black tank with black mesh briefs or black ice silk trunks. Sleek and impossible to get wrong.
- White and colour: white tank with green or red Low Rise Briefs. Fresh and summery, even in winter.
- Tone on tone blue: Deep Blue mesh tank with blue or dark blue mesh briefs. Looks like a designed set.
- Black and a pop: black tank with pink, sky blue or red underwear when you want one bright accent.

Getting the fit right on both pieces
A set only looks like a set when both pieces fit the same way: close to the body, no bagging, no digging in.
- Tank tops: the muscle tanks and the Ice Silky Vest are close-fitting. For a relaxed feel, the product pages suggest going one or two sizes up. The tanks run S to XXL; the Ice Silky Vest runs M to 3XL.
- Ice Silk Trunks: these run small, so size up. Waist guide: M fits 71-78 cm (28-31 in), L fits 76-84 cm (30-33 in).
- Briefs: the Low Rise Briefs and Breathable Mesh Underwear sit low on the hips and come in S to XXL.
A useful rule: the hem of the tank should reach the waistband of your underwear, or just past it. A gap of bare skin between the two breaks the "set" effect; a tank that bunches over the waistband looks untidy.
When to wear your set
- Under a shirt: a fitted tank in white or black disappears under an open collar and gives a smooth base layer, with matching underwear underneath.
- At the gym: changing rooms are where a coordinated pair is noticed most.
- Travelling: two or three tanks and matching underwear in one colour scheme pack light and mix freely.
- At home: a tank and trunks set is a comfortable lounge outfit on warm evenings.
- Special nights: a mesh tank with see-through mesh briefs makes a confident, put-together look for date nights.

Frequently asked questions
Do the tank top and underwear need to be the same colour?
No. Same colour is the simplest option, but a neutral tank with coloured underwear, or matching fabrics in different colours, looks just as deliberate.
Which underwear goes best with a mesh tank top?
Mesh briefs or low-rise briefs. They share the light, airy feel and the slim cut, so the pair looks balanced.
Can I wear a matching set under office clothes?
Yes. Choose a white or black tank with smooth underwear such as the Ice Silk Trunks; both stay discreet under a shirt and trousers.
Should I size up in fitted tank tops?
If you prefer a relaxed feel, yes. The product pages for our fitted tanks suggest one or two sizes up for a looser fit.
Build your own set
Start with a tank from our men's tank tops collection, then pick your colour or fabric match from men's briefs, mesh underwear or ice silk underwear. Every order ships in discreet packaging.
