For plus sizes, verify Lands’ Finish, and J.Crew — Talbots additionally used to hold it. For all suiting choices for ladies, try our roundup of the finest ladies’s fits of 2025!

What Is Seasonless Suiting?

The thought behind seasonless suiting is that it is, effectively, seasonless. This usually means wool, however a selected light-weight suiting materials that may really be worn even in summer season.

Can Polyester Depend as Seasonless Suiting?

I feel most individuals would take into account a wool swimsuit to be seasonless — however lately it is very onerous to discover a 100% wool swimsuit; a lot of the wool suiting supplies have a little bit of spandex woven into them for stretch.

Some manufacturers DO name polyester blends “seasonless suiting” — for instance, each J.Crew’s 4-Season Stretch and Ann Taylor’s Seasonless Stretch suiting is a mix of polyester, viscose, and spandex. On the plus aspect, the fits are machine cleanable!

Tremendous 120s

Years in the past you’ll discover a number of, for instance, J.Crew suiting that referred to as itself “tremendous 120s” wool — this tells you ways positive the material is. As Gentleman’s Gazette places it,

Tremendous numbers signify the fineness of the worsted wool fiber used within the cloth. The upper the quantity, resembling Tremendous 100s, 120s, or 150s, the finer the wool thread is. The precise quantity is calculated by the utmost variety of hanks of wool that may be spun into one pound of wool. For instance, when you can spin 100 hanks every 560 yards lengthy, the ensuing wool is assessed as Tremendous 100s.

As J.Crew used to notice,

Why so tremendous? 120 is the measure of the yarn (the upper the quantity, the finer the yarn), and since 120 is without doubt one of the most interesting, our cloth boasts a silky-smooth end and a refined drape.

The suiting materials remains to be round, in fact, however it’s tougher to search out manufacturers particularly claiming to make use of it, particularly since in the event that they’re speaking about their wool they’re extra prone to be telling you concerning the sustainability of it. (For instance, here is Idea’s web page on its “Good Wool.”)

Tropical Wool

“Tropical wool” is one other time period for seasonless suiting that you do not see fairly often proper now, however has been round previously — it usually meant wool that was so breathable you can put on it even within the tropics. I had at all times discovered these garments to be just about seasonless, although.

Correct Material distinguishes tropical wool from worsted wool, noting that the looser weave “will be light-weight too however can be woven to be heavier and applicable for year-round put on.”

What Is NOT Seasonless Suiting

You will note a number of completely different materials for fits lately… none of those are what they’re speaking about:

• ponte or scuba
• polyester blends
• “crepe” suiting
• linen
• cotton or stretch cotton
• tweed
• velvet

Brooks Brothers makes a number of ladies’s fits of the “enjoyable” selection, with a number of choices for shiny colours, patterns, and seasonal materials.

Their “Necessities” suiting, although, has been round for a very long time, and is value discussing right here — the wool/elastane mix is ideal as a seasonless swimsuit. As they observe,

These suiting separates additionally include a constant coloration assure, so the navy jacket you purchase right now will match the navy pencil skirt you buy subsequent yr, and past.

Ooh, the colour assure is sweet (though colours can change barely as you launder fits — it is one of many causes we advocate dry cleansing all items of ladies’s fits on the similar time/frequency). The fits can be found in primary colours, sizes 00-16.

Ann Taylor

Ann Taylor’s “seasonless stretch,” as we famous above, will not be really wool — it is a polyester mix. Nonetheless, that does imply it is machine cleanable. (Try our roundup on one of the best machine cleanable fits if that is of curiosity to you!)

They make it in a bunch of various colours, cuts, and kinds, so there’s one thing for everybody. For interviews, although, we would advocate sticking with darkish neutrals like black, navy, or darkish grey.

J.Crew’s “4-season stretch suiting” is one other one that isn’t product of wool, however as a substitute a polyester/viscose/elastane mix. J.Crew touts that the model contains “not less than 30% recycled supplies,” for what that is value. They describe their “well-known four-season stretch” as by no means dropping its form.

(They do HAVE suiting product of wool, however they are typically novelty fits as a substitute of their previous line of primary Tremendous 120s wool suiting.)

One profit to the newer suiting: J.Crew has prolonged its measurement vary to incorporate 0-24, in addition to a smaller vary for petites and tall sizes.

Lands’ Finish suiting part has been in flux of late, however they normally have their washable wool suiting in inventory.

The material is a mix of polyester, wool, and spandex, and it is machine cleanable. As they describe it, “the marginally stretchy, easy-care cloth [is] perfect for journey too. It’s going to bounce again after being packed in a garment bag, and by no means wants a visit to the cleaners — simply wash and dry.”

The fits are available common, petite, tall, and plus sizes in sedate colours.

Argent

Not like a number of the manufacturers we have talked about, Argent’s seasonless suiting line contains a number of shiny, saturated colours.

The model is accessible in sizes 0-14, and describes the fabric as “seasonless wool from Italy, 98% Wool, 2% Elastane.” (The liner is viscose/polyester.)

Bespoke garments are superior, however discovering your exact measurements will be difficult, so I might not essentially advise a beginner to offer this a strive. But when your measurements and are up for the journey of ordering bespoke fits on-line, go for it!
