GET THE LOOK: LYNN GUNN
Lynn wore this longline button up at Slam Dunk a couple days ago! Unfortunately, the EXACT one she’s wearing, from ASOS, is no longer available and they’ve replaced it with a newer model which can be found HERE

Although THIS is what replaced the one she was wearing, I don’t think that looks much like it. SO, I found some others that look a bit more similar.

Find the longline button downs HERE:
1. ASOS shirt in super longline with long sleeves ($40)

2. Monki longline shirt dress ($63)

3. BDG long button-down shirt ($59)
