I have one Sezane pullover, bought secondhand online and looks like it will wear well (it’s a 100% cotton knit). It’s an interesting brand; their look (a lot of very femme, 70s, vintage-inspired pieces, dainty florals and blouson sleeves) seems very on-trend, a French take on “cottage-core”? I’m between an XS and a S and this particular sweater fits well in a S; I wouldn’t want to go any smaller.
Ann Taylor is a US brand I associate with classic, mid-market office-wear. Their sister brand Loft does slightly more casual styles. Nothing too cutting edge, just solid and dependable. There is *a lot* of Loft and a fair amount of Ann Taylor in the thrift stores where I live. Seems to be the go-to for preppy young recent college grads buying clothes for their first real job, clothes which then get upgraded after a couple of years?
Storm I’m not familiar with; don’t think it’s available in the US.
