One tuxedo for year-round wear in Vietnam: choosing cloth weight

In the south, a single tuxedo in light-to-medium wool is enough to wear all year. In the north, where winter is properly cold, choose medium-to-heavy cloth, or add a second suit if you attend events in both seasons. To choose correctly, you first need to know what the weight figure on the bolt means.

What grams per metre means

Cloth weight is usually quoted in grams per metre, written g/m: how much one metre of length of the cloth, typically about 150 cm wide, weighs. Some English mills quote ounces per yard, and others give grams per square metre (g/m²), which divides by area. The units cannot be swapped directly, so when comparing cloths make sure the figures are in the same unit.

Weight does not tell you everything about how a cloth wears. An open-woven 270 g/m cloth can be airier than a dense 250 g/m one. It is a guide only, to be read together with the weave and the fibre, as our article on the Super number points out.

Light, medium and heavy

The ranges below are a common way of grouping, and mills may label them slightly differently:

Group	Approximate weight	Character
Light	Under about 250 g/m	Airy, soft, creases more, suits hot climates
Medium	About 250–300 g/m	Balance of airiness and structure
Heavy	Over about 300 g/m	Holds shape, warm, suits cold seasons

Light cloth drapes softly and feels cool, but lacks body unless the tailor builds the jacket carefully. Heavy cloth gives a crisp lapel line and shoulder, but in warm places the wearer starts to perspire early. Medium weight is the most common compromise.

The south: hot all year

In Ho Chi Minh City and the southern provinces there is no significant cold season. What you care about is heat and stuffiness. A light or medium-light cloth, openly woven, is the right call. The typical cloth for this need is tropical wool.

One point to bear in mind is that reception rooms are often air-conditioned very hard. So do not go too thin. A light-to-medium weight keeps a reasonable warmth when you walk into a chilled room, yet does not stifle you outside.

The north: a real cold season

In Hanoi and the northern provinces, the cold spells of winter can fall low, especially when an evening event is held outdoors. Consider medium to heavy cloth, with a thin undershirt or a waistcoat beneath. Our piece on wearing a tuxedo in cold weather explains how to stay warm without bulk.

The catch is that northern summers are just as hot and humid as the south. An overly heavy suit will be a burden in summer, so a medium weight is the safe course if you own one suit.

One suit or two by season

One suit is enough when:

• You live in the south and attend events spread through the year.
• You wear a tuxedo a few times a year and value convenience.
• You choose a medium-light cloth with a breathable lining, and perhaps add a waistcoat in cooler weather.

Two suits make sense when:

• You travel often between the two regions or abroad in winter.
• You wear a tuxedo frequently, as a performer, host or someone with many events, and need to rotate so the cloth can rest.
• You want a light suit for the hot season and a velvet or heavier wool one for the cold season. Seasonal colour is covered in tuxedo colours by season.

One honest note: for most people, a single suit made in the right cloth and the right cut is more useful than two middling ones.

Advice from the Mon Amie workshop

At the showroom, tell your consultant where you live, which occasions you wear it for, and whether you are usually in air-conditioned rooms or outdoors. From that the consultant can show swatches in a suitable weight. You can learn more on the made-to-measure tuxedo page and book a cloth viewing.
