What to wear at Infinity

seven nights, one code

Infinity opens every day and the house dress code is a single one: elegant attire. It applies all seven nights, the two themed ones included, which add their theme inside: lingerie at Monday's Velvet & Desire Night, and Thursday's FKK Night Party is spent without clothes. On both you arrive in elegant attire and change in the locker room.

The short version: make an effort. Nobody at the door is reading labels and expensive clothes buy you nothing here. What people notice is whether you got ready, or whether you simply turned up.

• Monday · Velvet & Desire Night — elegant attire (lingerie inside)
• Tuesday · Savage Party Night — elegant attire
• Wednesday · Couples Night — elegant attire
• Thursday · FKK Night Party — elegant attire (FKK inside)
• Friday · Hot & Thirsty Friday — elegant attire
• Saturday · Indulge in the Night — elegant attire
• Sunday · All For One Night — elegant attire

Elegant attire, in practice

Elegant here means what you'd wear to a good dinner out — a dress or a skirt with proper shoes, or tailored trousers with a proper shirt. A jacket works well and nobody misses it if you left it at the hotel. It isn't a gala or a costume, and nobody inspects you on the way in: it's enough that you've clearly made an effort.

One code, a different rhythm each night

The code doesn't change from one day to the next, but each night asks you to think about something different. Wednesday's Couples Night is the most conversational of the week, so dress for a long conversation rather than five hours on a dance floor. On Friday, Hot & Thirsty, and Saturday, Indulge in the Night, there's a DJ and the room runs until four: give the shoes as much thought as the rest, because heels that feel fine for two hours are a poor decision at half past two.

Saturday is also Infinity's big night, the one that draws the most people. Sunday, All For One Night, is the most explicit evening on the calendar and the one with limited numbers, so booking ahead is the sensible move. And Tuesday, Savage Party Night, is the wildest night of the working week. Every one of them starts from the same place: elegant attire.

Thursday · FKK: what a nudist night actually involves

FKK stands for Freikörperkultur, the German word for naturism, and it's used right across Europe. Thursday's FKK Night Party is exactly that: an evening spent without clothes, open to couples and to single women and men.

It's the night that stops most first-timers, and nearly always for the same reason — the fear of being the only undressed person in a room full of dressed ones. That doesn't happen, because the code applies to everyone equally. Ten minutes in it stops feeling strange, and it often turns out to be the easiest night of the week to relax into. You arrive in elegant attire, as on any other night, and change in the locker room; if you'd like to know how arrivals work that night, ask on WhatsApp before you come.

What doesn't work, any night of the week

Three things look wrong every time, and none of them is about money.

None of this is snobbery. In a room where people come over to talk to you, being clean and smelling good counts for far more than what the shirt cost. A shower, fresh clothes and a light hand with the fragrance covers most of the code on any night.

• Beachwear: swim shorts, flip-flops, the T-shirt you wore by the pool.
• Tracksuits, sportswear and trainers.
• Coming straight off the promenade without a shower.

You're on holiday and your suitcase is all swimwear

It happens every week. You pack for the beach at Maspalomas and then a plan turns up that asks for something else. It takes very little to fix: a plain shirt, dark trousers and closed shoes will carry you through all seven nights, and so will one simple black dress. Playa del Inglés is full of shops, and staying inside the code is not an expensive business.

If you're still standing in front of the wardrobe undecided, message +34 646 44 71 34 and ask. Much easier to settle on WhatsApp than at the door at eleven at night. Any taxi driver knows C.C. La Sandía on Avenida de Alemania, so actually getting here is the easy part.
