Black Tie Optional in Paris in June
The dress code, resolved against 22°C/72°F June weather and local custom · what Black Tie Optional means in general
The verdict
In Paris in June, Black‑Tie‑Optional means you can wear a tuxedo, but a lightweight midnight‑navy or charcoal suit with a black tie is the safest, climate‑smart choice that meets the code’s ceiling and floor.
Where the code meets the climate
- Black‑Tie‑Optional demands black shoes; Parisian guests often wear dark brown, but the code’s floor is black shoes, so choose polished black Oxfords.
- A dark tie can feel warm at 22 °C (71 °F); resolve by selecting a lightweight silk or fine‑wool tie and a breathable cotton shirt – the code bends on fabric, not on the tie itself.
- A full tuxedo jacket may be too hot for midday sun; the code allows a tuxedo but you may temporarily remove the jacket after the ceremony – keep it on for the church and dinner to respect etiquette.

“They did such an amazing job, my suit fits perfectly and the craftsmanship is superb! Linda was a great help and she knows exactly what she is doing. I can't recommend this place enough and I will be getting more suits from them in the future guaranteed!”
“Great place to get perfect suit, they send me to Poland with no problems.”
“WOW! Ordered a suit online with Linda. She contacted me by video call to go through the measuring process and once confirmed measurements again, around 4 weeks later a made to measure suit arrived in the UK. Fitted perfectly and I didn't even visit! Fantastic quality and customer service from Linda. Would definitely recommend!”
“Exceptional experience from start to finish. I ordered a fully custom two-piece double-breasted suit remotely from France, Linda and Jennifer guided me through every step with patience and professionalism. The suit arrived in under 3 weeks and the result is flawless: fabric, cut, lining, silhouette, everything is perfect. Nathan Tailors delivered exactly the vision I had in mind. I will absolutely be ordering again. Highly recommended.”
“This was my first time buying suits online so I was a bit apprehensive. However, the online order form was both easy to use and very thorough, and they did a video call with me to make sure of a couple of measurements that were out of the normal range. Two suits and a shirt arrived here in New Zealand in less than two weeks, are well-made, and fit perfectly. I'm thrilled with the service.”
Black Tie Optional in Paris: what guests ask
Can I wear a dark brown suit instead of navy or charcoal?
No – the code’s floor requires the darkest, plainest suit; navy, charcoal, or true black meet the rule, while brown would be below the floor.
Is a black bow tie allowed with a dark suit?
Yes – a black bow tie with a dark suit is the classic “almost‑black‑tie” move and satisfies the optional black‑tie ceiling.
What if it rains during the outdoor apéritif?
Your lightweight wool suit is water‑resistant enough for brief showers; keep the shoes polished black Oxfords with a thin leather sole for safe footing on wet cobblestones.
