If you haven't seen Dolce and Gabanna's Fall Runway or recent ads in Vogue, Elle etc. then you may not know that plaid on plaid is a bold trend for fall. I just did an Etsy search to see what fabulous vintage plaid items I could find as a cost effective and green alternative to this hot trend.
A bit pricey at $72, but I haven't seen anything quite like it. Decades
Not very old, but only $16. Muskoka Vintage
Quick this one is only $15! ElectricLime
I would shorten this one to a mini length, $28. Cositas Serias Vintage
High waisted shorts with suspenders for the stylistically brave, $28. Urban Lotus Boutique
Love this bag, only $17! Marcella's Excess
