Fashion Week isn’t only fabric and flashbulbs – it’s the energy you radiate between the shows; and few things broadcast confidence faster than a relaxed, camera‑ready grin. Here is a no‑nonsense game plan – rooted in real research (pun intended) – to keep your smile looking effortless when the street‑style photographers swarm.
Why a ‘Real’ Smile Wins Every Time
A genuine (Duchenne) smile fires up two muscle groups at once: the zygomatic majors lift the mouth corners, while the orbicularis oculi crinkle the eyes. According to studies in the Journal of Nonverbal Behavior (and broader reviews of Duchenne research), viewers instinctively rate those dual‑action smiles as warmer and more authentic than ‘mouth‑only’ poses.
Fake It Briefly, Feel It For Real
Can’t summon true joy on demand? Research has found that forcing a broad grin for just 20 seconds nudges our amygdala into a happier state; turns out there is some truth to the ‘fake it til you make it’ concept, after all.
Pre‑Show Smile Prep
As London-based cosmetic dentist Dr. Sam Jethwa BDS of Bespoke Smile advises:
“A well-timed whitening treatment a week before Fashion Week ensures your teeth look their best without sensitivity. Avoid red wine and coffee 48 hours post-treatment to prevent staining.”
| Quick Boost | Why It Works | Timing |
| Pro Whitening | 99.7 % of adults say an attractive smile is a prized social asset and whitening is the top ‘first‑choice’ improvement | 7-10 days out |
| At‑home strips | Safe carbamide‑peroxide formulas can brighten in 3-5 days | Finish 72 hours before Day 1 |
| ‘White‑diet’ rule | Skip coffee, tea, red wine & dark sauces for 48 hours post‑whitening to keep enamel from re‑absorbing pigments | 48 hours |
Lip TLC: The freshest of enamel is still a flop if your lips are cracked. Exfoliate gently with a sugar‑honey scrub, then seal with a balm high in ceramides – ideally overnight.
On‑Street Posing Hacks
- Find your three‑quarter angle. In a La Trobe University analysis of 2,000 Instagram selfies, over 40% of people subconsciously favored their left cheek – often perceived as the “more expressive” side. Try turning that cheek 30‑45° toward the lens for natural depth
- Think ‘eyes first.’ Micro‑squint as though you’re mid‑laugh; it engages those orbicularis muscles and instantly upgrades a polite grin to a genuine one
- Micro‑bursts, not marathons. Dynamic‑smile research in PLOS ONE shows that smiles judged most ‘pleasant’ peak quickly, then relax – so flash your grin in short hits instead of freezing for multiple shutters like a broken record stuck on the word ‘cheese’
- Half‑smile for haute‑cool. A relaxed, lips‑closed up‑turn (think street‑snap Bella Hadid) reads tres-chic when you’re feeling over‑posed
Smile‑Friendly Makeup Magic
- Play with undertones. Blue‑based reds and cool pink‑nudes create a subtle optical illusion that makes enamel look brighter, while warm corals or browns can do the opposite
- Add a pinpoint of light. Dabbing highlighter on the Cupid’s bow and the centre of the lower lip bounces light forward, amplifying that just‑whitened effect without a filter
- Choose finish by forecast. In harsh midday sunlight, a satin or demi‑matte lipstick photographs crisper than high‑gloss formulas, which can catch glare and obscure tooth lines
Hydration & Diet for an All‑Day Glow
- Crunchy fruit and veg are nature’s toothbrush. Biting into apples, celery or carrots boosts saliva flow and scrubs away soft plaque before it turns into calculus (otherwise known as tartar – a hardened form of plaque)
- Keep saliva on your side. Adequate hydration (think a refillable bottle between shows) lets saliva maintain a neutral pH and remineralise enamel, cutting decay risk
- Chew sugar‑free gum after street‑food stops. Clinical trials cited by the American Dental Association show that 20 minutes of chewing xylitol- or sorbitol-sweetened gum post‑meal measurably lowers cavity incidence
Handling Pap‑Pressure Like a Pro
- Breathe through the shot. Holding your breath tightens facial muscles and flattens your expression
- Cue a private joke. Genuine amusement softens the eyes and keeps the smile fluid
- Avoid ‘deer‑in‑headlights’ eyes. Look just off‑lens, then snap back to add life to your gaze

After‑Hours Muscle Rehab
Smiling for dozens of runways can fatigue even well‑trained zygomatics (cheek bones). At night, try:
- Warm‑cloth compress: 5 minutes over cheeks and jaw to loosen tight fibers
- Hydration check: Street Style equals constant coffee; swap the last latte for water to keep lips plush
- Mini facial massage: Gentle circular strokes from nose to temples release the orbicularis tension
Smile Like You Mean It
No amount of couture outshines authentic confidence. Nail the basics – bright teeth, hydrated lips, a left‑cheek tilt and smiles you feel – and the lenses will love you. Remember: the best street‑style accessory is free, fits every outfit and starts behind your eyes.
