You have problems finding accessories, clothes, Interior, .. and there is no 'Gothic store' close to you. Or no online shop you can use?
Simple trick :P
'KEEP YOUR EYES OPEN'
You won't believe how many things you can find in the 'normal world' that fit your style.
Go to H&M's, C&A's .. yes even Claire's !
Spiders, Crosses, Fairys, Lace, Velvet, ..
