I just want a good quality (thick fabric), slim fitting, long t-shirt with short sleeves and a proper, deep scoop neck.

The holy grail that is impossible to find.

They either have no sleeves, long sleeves, not a proper scoop, silly cut outs on the back, are too short or have thin fabric.

It's such a flattering style that I don’t understand why it’s so hard to find.

Uniqlo do super thick long-sleeved tops.

Except that's not what the OP wants. 😂

Well - not sure purists will like this but I’ve found these great T-shirts on Amazon (not scoop neck exactly…)

Scoop necks only seem to come with long sleeves or no sleeves (vest).

I need short sleeves (can reach my elbow or be shorter, but preferably not capped.

Thank you, but these are nowhere deep enough in the neckline.

Rapanui any use? Not super, super thick, but the white one I have on now is nowhere near see through.

They’re better, but not deep enough. I’ll try to find an image.

This sort of scoop neck, but much, thicker fabric, longer in the body and longer (but still short sleeves).

I'm an hour-glass and the scoop neck is the most flattering for my big boobs. Short sleeves helps to balance out the look. I need the long body to counteract my shape - otherwise it ends up pulling down and showing too much cleavage, or riding up my belly.

You might have better luck getting a short sleeved scoop neck bodysuit rather than a T-shirt if you can tolerate bodysuits

I think you are struggling because scoop necks haven’t been very fashionable for a few years. They’ll come back and then you can stock up

I’ve got these, I find them a bit short in the body as I’m tall but they are the only scooped neck t shirts I could find.

Unfortunately, I have a long body and have never got on with these. I even struggle getting one piece swimming costumes that fit properly.

I have the same problem. Next have some scoop neck short sleeve white T-shirts

They are not cheap but CitizenWolf make a short sleeve tee with a scoop neck. And they customise.

This one from Next?

The M&S ones are pretty thin though.

I know exactly what you mean OP. Im currently wearing the last one I have ..bought from M&S 7 years ago and still going strong. But they dont do anything like them now.

I’m busty too op and similarly frustrated. They make bejillions of ‘classic’ t shirts in all colours but who do they really suit apart from men? They’re certainly not flattering.

I’ve had some luck with the La Redoute scoop neck t shirts but they’re quite thin. I think like the pp said, that low 90s style scoop just isn’t in fashion atm so you will struggle.

I agree such a useful and flattering shape. I hate to recommend Sunspel as they are so expensive but the quality is a cut above. I have worn my one of these for many years and its still in perfect shape. The slash neck is generous and hangs a little on me so I find it as nice if not better than a scoop

The also do a proper scoop neck but the fabric is stretchy which Im not sure youre after.

I've been looking for exactly this for ages. As far as I can see, they don't exist except at M&S but I don't rate their t-shirts at all. :(

Gap has some t shirts with a decently deep V that aren’t too short as an alternative that might work for your bust?

Kettlewell might not be deep enough of a scoop but they have them.
