Breton style top / long sleeve t shirt in plus size? Does it exist?

[Germgirl]

I'm fat, getting smaller, lost 6.5 stone recently and would like to dress better, I had some brilliant advice on S&B recently and have been buying a few bits.
I'd love to try the 'MN uniform' of long sleeve t shirt / stripy top thing with skinny jeans and a scarf. I've got the jeans (thank you sainsburys!) but I'm lacking tops.
Sadly my bottom half is shrinking at a much faster rate than the top. I'm size 20 bottom and 26/28 top.
I've looked at all the 'fat lady' shops online but can't find any nice long sleeve t shirt tops.
They need to be pretty long to cover my horrible front bum stomach. All the ones I can find in places like Yours and Simply Be are too short.
Do any 'normal' shops or websites do clothes in size 26/28? Or am I stuck in my shapeless tunics for a bit longer?

Try ASOS Curve? Their clothing runs large too. I'm a 22-24 and have one from Sainsburys actually, but it's not a long one.

I did have a look on there. I'll look again. Thanks.
I love Sainos for bottoms but don't fit in the tops yet :)

This is a longer length style but might suit Dorothy Perkins Curve

this is nice OP. Bloody well done btw - 6.5 is amazing.

I'm a size 18, and currently wearing..... Skinny jeans and a Breton top! Though my top is genuine, bought in France (smug)
I don't go for a scarf, as I'm pretty busty so with stripes and scarf and boobs it's just too much going on! Much prefer it without

The weight loss was achieved by surgery. Not willpower I'm afraid (although you need plenty of that too)
That DP one is lovely. Thank you. The Asos one looks a bit short, but again, thanks.
H&m wasn't somewhere I thought of looking, or DP, this is what I meant, I don't know which 'normal' shops do bigger clothes.
Thank you so much, I'm going to order the DP top & have a look at what else they have.
Thank you again :)

Curls my boobs have just about vanished ! I'm a ball on legs. I like a scarf because most of what I wear is black, black & more black so I add a bit of colour with a scarf.
And if I wear them long enough, they cover the gut too! :)

Is this nice or hideous? Will it make me even more ball like?

I don't think it's hideous, but I would think the high small neck and the bold line straight across the widest part wouldn't be very Flattering on most people, regardless of size! But, would be worth trying on as it could be nice
