Rose 15x30: Houston, We Had a Problem

Cardigan - Aubainerie
Button-down - HM
Cami - HM
Belt - Thrifted
Skirt - RW&CO
Shoes - Aldo

I really like this button-down (or actually, button half) shirt but I have a hard time wearing it. It's a bit tight in the bust area and I hate wearing white underneath, so I went with this tangerine-white striped cami and I am quite pleased with the result.
