Thin undershirts for nice tops

[DreadPirateRobots]

I'm being heavily advertised the thin Numi undershirts for wearing underneath your nice quality delicates and protect them from sweat, etc, but the postage from the US is 😱. I like wearing silk shirts and nice wool and would like something other than the standard camisoles I currently have to wear underneath. Preferably nonbulky, short sleeved for underarm cover purposes, and scoop or v necked so it doesn't show under a buttoned shirt. Any recs?

I just buy light weight scoop neck t shirts from the likes of uniqlo. I usually buy a couple of sizes too small so that they are tight fitting.

M&S short sleeved thermal vests. Last year's ones had low scooped necks. Also look for Uniqlo thermals - they are thin material. I always have one of these on under clothes in winter time to protect jumpers and keep me warm.

Thanks, I do have some m&s scoopnecked sleeveless vests which are quite nice. I'd ideally like to get something fleshcoloured. Might look at the Uniqlo AIRISM stuff.

Ugh, I can't really see anything on either Uniqlo or M&S with a sufficiently low scoopneck 😥i have a thin knitted body from Intimissimi which is sort of good but turns your knickers into a wedgie.

New look seem to have some very low scoop necks at the moment although I find that if you buy the uniqlo ones a couple of sizes too small you can pull them right down and they stay out of sight.
