Persols in the Chicago Nordstrom Rack stores (Chicago Ave location for sure). I picked up another pair of 649s. For $80 I couldn't say no even though I already have them and 714s.
Also, the Drake's items at East Dane (a streetwear boutique not really repped on MC ever) are pretty darn cheap (scarves and ties). Additional 25% off with some code that is on the site. 25extra maybe? Idk. Anyway, ties are in a more traditional width (9 cm).
