Women's blazers

Women’s Blazer Tailored, Chiang Mai: the standalone garment

Women’s blazers are bought as part of suits and worn as separates. That gap between how they are sold and how they are used is worth designing around.

A blazer that lives its life over dresses, jeans, trousers of a different colour and knitwear has different requirements from a suit jacket. It wants to look complete on its own, which argues for cloth with some texture or interest, and for a length and shape that work over more than one thing.

Say how you actually intend to wear it, because it changes the cut.

Solve the closure

The most visible fit failure in women’s tailoring, and the one that most clearly separates a made jacket from a bought one.

A jacket whose lapels point away from the chest, or which pulls into horizontal creases at the button, does not have enough room across the bust. The pattern was drawn for a smaller bust-to-shoulder ratio than yours.

The industry workaround is to design jackets that are only ever worn open, which quietly concedes the problem. A properly drafted jacket, using a bust dart or a princess seam placed to your actual apex, closes cleanly and looks correct both open and fastened. That is what you are buying.

Shoulder first, as always

The shoulder seam should end at the outer point of your shoulder, with the sleeve falling cleanly from it.

It is the one dimension that cannot be altered afterwards without rebuilding the top of the jacket, so it is fitted first and everything else is drafted around it. A jacket bought to fit the bust with shoulders two sizes too wide is the most common compromise in ready-made womenswear, and it reads as borrowed.

Length and shape

Hip length is the most versatile and works over trousers, skirts and dresses.

Cropped is a strong style choice, works well over high-waisted trousers, and is less flexible.

Longer, tunic length reads as more contemporary and needs some height to carry.

A single-breasted jacket with a moderate lapel is the versatile default. A double-breasted jacket is a stronger statement and must stay buttoned.

Cloth

Wool crepe deserves particular mention. It resists creasing, holds a defined shape, drapes cleanly and is more breathable than it looks, which makes it excellent for this climate.

Lightweight worsted works well, particularly if the blazer needs to match suit trousers or a skirt cut from the same roll.
