Nice maternity t shirts

[Teachermaths]

I'm looking for some plain yet decent quality maternity t shirts. I had a look in jojo but they're all patterned or striped. Primark and h&m are so thin you can see through them.

Any ideas for basic plain maternity t shirts?

Seraphine? Unless it’s all changed in the last 5 years the sizes are true to pre pregnancy sizes and things wash really well.
