Sweatproof Scoop Neck Undershirt (Nude)

I'm actually pretty impressed with these undershirts. I found the sizing a bit small, so organised a return and found customer service very helpful. The new size fit perfectly. I'm normally a 10/12 and had to get a Large. I was worried the texture would feel horrible and plastic, but it's actually very comfortable. It also serves it's main function of soaking up sweat and I don't have patches on my work shirts now.
I really want a scoop top in black now, but they don't have any. Please add more colours.

Plenty of clothing say they are sweat proof but I am always still left with sweat marks thanks to extreme sweating from hormones and medication. These tops genuinely stop the marks and free me from the embarrassment! Will be stocking up on more.

Nice colour, nice material but sent back as not true size, awaiting on exchange in larger size

I have tried to exchange my tops but with no success
The tops are lovely material but a bit see through
Wish I had sized up
