I have been stalking these shirts for months now but until the 4Worn launch, I just wasn't able to get over the price hurdle for me. I couldn't hit "buy" fast enough when 4Worn launched.
I purchased the legacy version because I like a more crisp look. Wore it to a casual party and got a compliment immediately on the unusual texture. It's also super warm! When this arrived, I took off what I was wearing -- a shirt plus a very chunky cotton sweater -- to try this on, and the 4 work shirt ALONE was warmer. As someone who always runs cold, this is amazing. I assume like any wool, this is thermoregulating and will not be too hot for most of the year.
The cut and length are good, as well as button placement. I got a size 1, which fit super well for me (5'4", 112 lbs, small bust).
Also I have very itch-sensitive skin (as a comparison point, baby alpaca sweaters make me itch, but merino wool products are generally OK for me). This shirt does not bother me even though it is not super soft in the traditional sense. Again, this is the older style of this shirt with a fabric that is supposed to be more polished but less soft.
