It is a must. Every year I ask my students to post photos taken in la feria, but you can´t show a glass, or a cigarette and you must wear the tradititional outfit for la feria, that is, flamenca gown for girls, and suit for boys, unless you ride a horse, you know: politically correct....
Send me a photo to paulavallejogonzalez@gmail.com and from there I will be able to post it here.
Happy feria!!!!
