Found a T-shirt in a thrift shop with similar pattern as my broken striped top but in black stripes. I refashioned into a T-shirt for Sidra. The original top is not very big, so I use black jersey from other T-shirt for the sleeves.
The pattern is PDF pattern called Biscuit from Tamanegi Kobo, a Japanese pattern shop. It is quite an interesting pattern because the front looks like ordinary T-shirt while from the back it looks like a raglan sleeves T-shirt.
