Module 21: Fashion

Fabrics, brands, dress codes, and style

Part A · the fashion industry pyramid
Four tiers — the same brand sometimes occupies multiple levels
Haute couture — hand-crafted, made-to-measure, one client at a time
Chanel, Dior, Valentino, Givenchy. A single couture dress: €10,000–€200,000+. Legally protected designation in France. Only ~15 official haute couture houses. Shows twice yearly in Paris. Serves ~2,000–3,000 clients worldwide. Exists primarily as marketing for the brand's perfume, beauty, and accessories lines — which actually make money.
Luxury / ready-to-wear — designed in-house, manufactured to high standards, high price
Louis Vuitton, Gucci, Hermès, Prada, Burberry, Versace, Saint Laurent. Items: €500–€5,000+. Sold in own boutiques and high-end department stores. Quality materials and construction; distinct brand identity. The "aspirational luxury" tier where most luxury revenue is made.
Premium / contemporary — quality above high street, accessible luxury
Ralph Lauren, Tommy Hilfiger, Hugo Boss, Calvin Klein (mainline), Ted Baker, Reiss. Items: €80–€800. Good quality, brand recognition, sold in department stores and own shops. The sweet spot for most aspirational shoppers.
High street / fast fashion — trend-driven, low-cost, high-volume, rapid cycles
Zara, H&M, Uniqlo, Mango, Primark. Items: €5–€100. 52 "micro-seasons" per year (Zara). Global supply chains. Environmental and labour concerns. Zara's model (design-to-shelf in 2 weeks vs industry's 6 months) revolutionised the industry.
The great irony: Haute couture exists to fund perfume. A Chanel No.5 perfume (€120) funds the €200,000 dress that funds the brand's prestige that sells the perfume. The entire pyramid depends on each level signalling upward aspiration.
Part B · the three fashion conglomerates that own almost everything

Part E · dress codes decoded
Part F · tie vs bow tie — and how to wear both

Necktie (regular tie)

Business and formal events

Width: slim (5–6 cm) for modern/fashion; classic (8–9 cm) for business; wide (10+ cm) is dated. Length: tip should reach the waistband of your trousers — not above, not below. Knots: Four-in-hand (simple, slightly asymmetric), Half Windsor (medium, triangular), Full Windsor (large, symmetrical — for spread collar shirts). Dimple: a single indent just below the knot signals intentionality and care. Worn with: business formal, business casual with jacket, smart events, funerals.

Bow tie

Black tie and above (or confident casual)

Always self-tied (never pre-tied clip-on at formal events — the small imperfection of a hand-tied bow is the point). Black silk for black tie events. Patterned/colourful bow ties for parties or confident daywear. The bow tie signals: either very formal (tuxedo context) or deliberate eccentricity (day wear). Size: the ends should not extend beyond the outer corners of the eyes. Worn with: black tie required, white tie required, or as a conscious statement with a suit.

Part G · fast fashion — what it is and why it matters

The Zara model

Design to shelf in 2 weeks

Inditex (Zara's parent, founded by Amancio Ortega, Spain) revolutionised fashion by cutting lead times from 6 months to 2 weeks. In-house designers, owned factories in Spain/Portugal/Morocco, centralised logistics from Arteixo, Spain. Result: 500–1,000 new styles per week, always fresh stock, never marked down (unsold items destroyed or donated). Creates artificial urgency — "buy it now or it's gone."

The environmental cost

Fashion = 10% of global CO₂ emissions

The fashion industry produces ~92 million tonnes of textile waste per year. A single polyester T-shirt sheds ~700,000 microplastic fibres per wash. The average garment is worn 7–10 times before being discarded (down from 200 times in the 1970s). The Congo (DRC) mines cobalt for dyes; Bangladesh's Rana Plaza factory collapse (2013, 1,134 dead) brought labour conditions to global attention.

Ultra-fast fashion (Shein model)

AI-driven demand → 10,000 new items/day

Shein (China, ~$66B valuation 2023) uses real-time trend algorithms to produce items in days, priced at €5–€20. Ships directly from Chinese factories. Bypasses import duties via "de minimis" exemptions. Faces scrutiny for IP theft (copying independent designers), labour conditions, and hazardous chemicals in garments. Represents the endpoint of the fast fashion model.

Sustainable alternatives

Slow fashion and second-hand

Patagonia (USA, B Corp) built its brand on environmental activism — "Don't buy this jacket" ad campaign. Vinted, Depop, ThredUp (second-hand marketplaces). Rent the Runway (dress rental). The resale market is growing 3× faster than regular fashion. Uniqlo's LifeWear philosophy (Japan) focuses on quality basics designed to last years, not seasons.

Part H · test yourself

1. You're invited to a "black tie" dinner. You don't own a tuxedo. What exactly do you need, and what are the acceptable alternatives?

The traditional requirement: black dinner jacket (tuxedo jacket) — single or double-breasted with silk or satin lapels, matching black trousers with a satin stripe down the leg, white dress shirt with a pleated front or bib, black bow tie (self-tied), black patent leather shoes, black cummerbund or waistcoat. Acceptable alternatives if you don't own one: (1) Hire a tuxedo — most formal hire shops provide the complete package. (2) Dark navy suit (not black suit — counterintuitively, a dark navy suit reads as more intentional than a black lounge suit, which looks like you misunderstood the dress code). A white pocket square and black bow tie signal the effort. (3) Morning dress is not appropriate for evening black tie — wrong time of day. What is never acceptable: a black lounge suit with a black tie (that's business formal, not black tie). The invitation saying "black tie preferred" gives more latitude than "black tie required."

2. A European woman wears EU size 40 in clothing and EU size 39 in shoes. What are her US sizes?

Clothing: EU 40 women's = US size 10 (approximately). The general rule: EU women's clothing size minus 30 = US size. So 40 − 30 = 10. This is approximate — brands vary. Shoes: EU 39 women's = US size 8. The rule for women's shoes: EU size minus 31 = US size. 39 − 31 = 8. For men's shoes the offset is different: EU 43 = US 10 (EU minus 33). Important caveat: these are guidelines. Italian sizing, French sizing, and UK sizing all differ slightly. A Zara EU 40 may fit differently from a Chanel EU 40. Always try on or check the brand's specific size chart.

3. What does a "16½" shirt collar size mean, and what measurement does it correspond to?

It's in inches — the circumference of your neck measured at the base. 16½ inches = approximately 42 cm. The collar should allow one finger between the collar and your neck when buttoned — tight enough to look neat, loose enough to breathe. In European/continental sizing this shirt would be labelled "42" (for 42 cm neck). Common sizes: 15" (38cm) small, 15½" (39.5cm) medium, 16" (41cm) medium-large, 16½" (42cm) large, 17" (43cm) XL, 17½" (44.5cm) XXL. Shirt sleeve length is a separate measurement: "32/33" means the sleeve length is 32–33 inches (81–84 cm). A full shirt size notation like "16½ / 33" tells you both collar and sleeve.

4. What is the difference between LVMH and Kering, and which owns Gucci?

Both are French luxury conglomerates. LVMH (Louis Vuitton Moët Hennessy), controlled by Bernard Arnault, is the world's largest luxury group with ~75 brands including Louis Vuitton, Dior, Fendi, Bulgari, and Moët & Chandon. It spans fashion, wines and spirits, watches and jewellery. Kering, controlled by François-Henri Pinault, is smaller but elite in fashion specifically — it owns Gucci, Saint Laurent, Bottega Veneta, Balenciaga, and Alexander McQueen. Gucci is Kering's most valuable brand and generates roughly half of Kering's total revenue. The rivalry between Arnault and Pinault for luxury supremacy is one of the great business competitions of the past 30 years. Hermès, notably, remains independent and family-controlled — Arnault once attempted to acquire a stake, leading to a legal battle that Hermès won.

5. What is the difference between "smart casual" and "business casual" — and why does it matter?

Business casual is for professional office environments — the goal is to look polished and work-appropriate without a tie. It typically means: collared shirt (button-down or polo), chinos or tailored trousers, leather shoes or clean smart shoes. No jeans (in most interpretations), no trainers, no T-shirts. Smart casual is a broader social code — the goal is to look intentional and put-together for a restaurant, party, or casual event. It allows well-fitted dark jeans, a clean shirt or smart knitwear, Chelsea boots or clean trainers. The key distinction: business casual is constrained by professional context; smart casual has more personal expression but still requires deliberate choices. The reason it matters: arriving underdressed at an event signals either you didn't know the code (ignorance) or didn't care enough to follow it (disrespect). Overdressing is almost always better than underdressing.
