Lane Bryant

Lane Bryant does not make a bra called Lane Bryant; every bra in the store is Cacique, its own house line, on a cup ladder that inserts an F where the US standard writes G. The fit guide measures the band honestly. Here is what that means for the size you will be given.

Lane Bryant is the best-known plus-size apparel chain in the US, and its lingerie department sells one brand: Cacique, designed in-house for bands from 34 to 54 and cups from B to K. Sizing questions about "Lane Bryant bras" are therefore questions about Cacique, and the Cacique dossier on this site documents the chart, the grading and the conversion trap in detail. This page covers the two things people search for under the store’s name: the measuring method in its fit guide, and the fitting service in its stores.

The method

How the Lane Bryant fit guide measures

The published guide is close to this site’s method. It has you wear a lightly lined, non-push-up bra, wrap the tape directly under the breasts, level with the bottom of the band, and read that as the band; then wrap the tape around the fullest part of the bust and subtract the band, at one inch per cup. Nothing is added to the underbust, which puts Lane Bryant on the right side of the add-four divide and is why its sizes translate to a measured size with only one adjustment.

The adjustment is the cup alphabet. The guide’s ladder runs 2 inches B, 3 C, 4 D, 5 DD, 6 DDD, then 7 F, 8 G, 9 H, 10 I, 11 J, 12 K. The US standard used on this site runs 7 G, 8 H, 9 I. So a Lane Bryant F is a US G, a Lane Bryant G is a US H, and every letter above DDD sits one rung earlier on their tag than on a Panache, Wacoal or Elomi tag for the same body. Convert by position, never by letter, and the widget on the Cacique page does it from your measured size.

The guide’s own chart also says that between two sizes you should take the smaller for a tighter fit or the larger for a looser one. On the band, take the smaller: a loose band is the failure the sister-size chart on each product page exists to fix.

Your measured size on a Lane Bryant tag

Enter your measured US size and the tool reads it on the Cacique ladder, with the UK and EU labels for the same body and a note on whether the store cuts it.

In practice

The in-store fitting

1Free, walk-in, tape and try-on

Lane Bryant stores offer free fittings without appointment. Fitters measure by the guide above and then bring styles to try; ask for a second cut in the same size before deciding.

2Sizes on the rail: 34 to 54, B to K

Below a 34 band the store has nothing to fit you into; a measured 30 or 32 will be shown a 34 with a smaller cup, which is a sister size two steps out. Above a K cup the range ends.

3Check the result

Enter your two measurements and the size the fitter wrote on the professional fitting page; it says whether the number came from your body or from the rail, and converts the Cacique letter to the US standard.

Answered

Lane Bryant: answered

Does Lane Bryant add inches to the band?

No. The published fit guide measures the band directly under the breasts and uses that number, which matches the snug method on this site. The difference between a Lane Bryant size and a measured size is in the cup letters above DDD, where Cacique inserts an F at seven inches.

What is my Lane Bryant bra size?

Your measured band, and your measured cup read on the Cacique ladder: DDD at six inches, F at seven, G at eight, H at nine. A measured 38G (US) is a Lane Bryant 38F; a measured 40H is a 40G. The Cacique page converts any measured size to the tag.

What bra brand does Lane Bryant sell?

Cacique, its own line, designed for bands 34 to 54 and cups B to K. Lane Bryant does not stock other bra brands, so "Lane Bryant sizing" and "Cacique sizing" are the same thing.

Is a Lane Bryant bra fitting free?

Yes, in store, without an appointment and without an obligation to buy. Fitters use the guide’s tape method and a try-on. Walk in knowing your measured size so you can tell a size that came from your body from a size that came from what is on the rail.

Does Lane Bryant carry small bands?

The Cacique range starts at 34. A measured 30 or 32 band will be fitted into a 34 with a smaller cup, which rides up; the smallest-band specialists are listed on the 28 and 30 band pages.
