What Is Seasonless Suiting?
The thought behind seasonless suiting is that it is, nicely, seasonless. This usually means wool, however a selected light-weight suiting materials that may really be worn even in summer time.
Can Polyester Depend as Seasonless Suiting?
I feel most individuals would take into account a wool swimsuit to be seasonless — however nowadays it’s extremely arduous 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 facet, the fits are mechanically cleanable!
Tremendous 120s
Years in the past you’ll discover plenty of, for instance, J.Crew suiting that known as itself “tremendous 120s” wool — this tells you ways wonderful the material is. As Gentleman’s Gazette places it,
Tremendous numbers characterize the fineness of the worsted wool fiber used within the material. The upper the quantity, akin to 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, in the event you can spin 100 hanks every 560 yards lengthy, the ensuing wool is classed 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 material boasts a silky-smooth end and a refined drape.
The suiting materials remains to be round, in fact, nevertheless it’s more durable to seek 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 up to now — it usually meant wool that was so breathable you may put on it even within the tropics. I had all the time discovered these garments to be just about seasonless, although.
Proper Cloth distinguishes tropical wool from worsted wool, noting that the looser weave “could be light-weight too however will also be woven to be heavier and acceptable for year-round put on.”
What Is NOT Seasonless Suiting
You will notice plenty of totally different materials for fits nowadays… none of those are what they’re speaking about:
- ponte or scuba
- polyester blends
- “crepe” suiting
- linen
- cotton or stretch cotton
- tweed
- velvet

Ann Taylor


Ann Taylor’s “seasonless stretch,” as we famous above, just isn’t really wool — it is a polyester mix. Nonetheless, that does imply it is mechanically cleanable. (Try our roundup on the best machine washable suits if that is of curiosity to you!)
They make it in a bunch of various colours, cuts, and types, so there’s one thing for everybody. For interviews, although, we would advocate sticking with darkish neutrals like black, navy, or darkish grey.

It will bounce again after being packed in a garment bag, and by no means wants a visit to the cleaners — simply wash and dry.”
The suits are available common, petite, tall, and plus sizes in sedate 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.)
