Could anyone help me with where they find comfortable bras for a smaller child/teen? We got Next 30A but the band is digging into her rib cage and leaving red marks under her arm pit, however she's only measuring as 25" around the ribs and 27" around the bust and going larger just means it gapes on her. She does have some sensory issues due to autism and is very bothered by the marks left when she takes off the 30" band. She is 136cm tall so really dinky compared to most of her peers but does need a little more than crop tops now.
M&S measuring lady just said they didn't stock anything small enough and our local independant has closed down.
Thanks for your help
