Bias-Cut Triacetate Slip Dress

A slip dress is the easiest thing in a wardrobe to get wrong, because there is nowhere to hide: no collar to distract, no seam to take in. This one is cut on the true 45-degree bias, which the maker names in its own process field (工艺 45度斜裁), so the triacetate falls as one sheet rather than hanging off the shoulders — it narrows at the hip because the weave does it and not because a dart was sewn in. The fibre is declared as 三醋酯纤维（三醋酸）:72% with 涤纶:28%, the only percentage-graded fibre in this round. That is triacetate, the fibre this market usually sells as 醋酸 and sometimes as Japanese acetate; the headline here says 日本醋酸, but nothing in the table says where the yarn was spun, so we have not repeated it. It is pull-on, with an adjustable slider on each strap, and the hem clears the floor by a little in every photograph. The maker lists eight colourways; seven are photographed above and only those seven are offered. There is no lining field in the maker’s table and no measurement table behind the S–2XL range, so neither is claimed here. A hang tag is fitted and no brand label is (领标 无领标), which is worth knowing if you intend to put your own name on it.

Bias cut, and the maker is willing to name it

Most slip dresses in this market are cut on the straight grain and described as draped, because straight panels fall flat and cost less cloth. This listing puts 45度斜裁 in its process field and the photographs bear it out — the cloth runs diagonally across the body, which is why the dress narrows and opens again without a single dart. Bias cutting wastes more fabric and is slower to sew than cutting on the straight, and that is a large part of what the price is buying.

Triacetate, which is not the same as acetate

The headline sells 日本醋酸. The fibre field underneath says 三醋酯纤维（三醋酸）72% and 涤纶 28% — two different fibres with confusingly similar names. Triacetate takes a heat-set lustre, resists wrinkling better than diacetate and is the one the Japanese mills are actually known for. Nothing published states where this yarn was spun, so the entry stops at the fibre and leaves the country of origin out.

Two things the maker does not publish

Whether the dress is lined is absent from the table entirely, so it is written here as unconfirmed rather than guessed from the photographs. So are the measurements: five sizes are listed and no bust, waist or length figure is given for any of them. Both are questions for the written quote, which is where this maker answers anyway — and neither is a reason to put a number on the page that nobody published.

Details

• Colour: Champagne · Pearl black · Cherry pink · Ivory · Dark grey · Red · Sky blue
• Size: S, M, L, XL, 2XL — the maker lists five sizes and publishes no measurement table behind them
• Material: 72% triacetate, 28% polyester. The maker declares 材质成分 as 三醋酯纤维（三醋酸）:72% · 涤纶（聚酯纤维）:28% — the only percentage-graded fibre in this round
• Fit: Slim through the body (修身型) on a relaxed waist (宽松腰), pull-on with no fastening (门襟 套头)

Care

• The maker publishes no washing symbol for this dress. Ask before retailing it — that is a quote question, not something to be read off the photographs.
• Triacetate is heat-sensitive and glazes under a hot iron. Press it cool, on the reverse, or steam it on the hanger.
• Bias-cut cloth stretches under its own weight. Fold it on a shelf rather than leaving it hanging for months.

Why we chose it

Because it is the only garment in this sweep that declares its fibre as a percentage in the material field, names the 45-degree bias cut in the process field, and then shows that cut in the photographs — and because at 320 units the maker is selling to people who are not buying on price.

Wholesale only — minimum 10 units per style, quoted by a person. Sample first, then scale.
