That's almost a dusty rose colour to my eye -- a little warmer, maybe. Not soul sucking beige. If it works, it will work brilliantly. But it does feel a little risky. I guess it is similar to blush in that respect -- hard to predict. I think XL in this could work for you if you are wearing a cami and don't mind oversized. It drapes terrifically so is easy to size up in without issue.
The tees and sweaters are quite different. Note, my sweater is a V-neck in garment dye -- I'm not sure if the other sweaters are similar. I think the V-neck is the longest of the three -- I'll put it in this post so you can compare.
The sweater is a heavier gauge knit than the tee. Still sheer and light, but a definite "sweater" vs. a "t-shirt." The linen tees are shorter (but not super short...on me they come close to crotch point, I think -- you can see in the pictures).
I don't think the tee runs more fluid than the V sweater. If anything, the sweaters are cut more square and boxy -- the tee is loose, but shaped like the body.
I just wanted an oversized fit in the sweater so ordered up. (Plus, I was a bit hesitant about sweater fit after finding the Tippi in my regular size too fitted for my current taste).
Also, there is "wiggle room" with the tee, because you can wet it and stretch it out a bit on a hanger if you want more fluidity.
I like both the sweaters and the tee. The tee is much easier to wear as a layering piece under a jacket. The sweater feels more like a topper in itself -- but that, again, is the V neck sweater, which is longer in the back -- the boatneck sweater has a different cut and might feel more versatile. The V-neck (oversized as I got it) almost feels like a boyfriend sweater. Whereas the tee feels like an under-jacket layering piece that can also stand very well on its own.
