For plus sizes, verify Lands’ Finish, and J.Crew — Talbots additionally used to hold it. For all suiting choices for girls, take a look at our roundup of the finest girls’s fits of 2025!
What Is Seasonless Suiting?
The concept behind seasonless suiting is that it is, properly, seasonless. This typically 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 believe most individuals would contemplate a wool swimsuit to be seasonless — however as of late it is very 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 machine cleanable!
Tremendous 120s
Years in the past you’d discover a whole lot of, for instance, J.Crew suiting that referred to as itself “tremendous 120s” wool — this tells you the way advantageous the material is. As Gentleman’s Gazette places it,
Tremendous numbers symbolize the fineness of the worsted wool fiber used within the cloth. The upper the quantity, comparable 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 case 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 likely one of the best, our cloth boasts a silky-smooth end and a refined drape.
The suiting materials continues to be round, after all, however it’s more durable 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 in regards to the sustainability of it. (For instance, this 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 typically meant wool that was so breathable you possibly 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 “might 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 note a whole lot of totally different materials for fits as of late… none of those are what they’re speaking about:
- ponte or scuba
- polyester blends
- “crepe” suiting
- linen
- cotton or stretch cotton
- tweed
- velvet
