Hi there! Im not sure about the Wild West Clothing, since i never paid attention with the armor clothings until the Anbu Armor came .. But as far as i know, some clothing fragments appears in some events like Konoha Limited Shop, or the Daily Special which gives discounted prices .. And about getting clothing, its best to know what the best for you, or depends on your needs, for example, you want to get more power then go and get Anbu Armor since it gives 300nin300atk, if you need initiative then get summer break or wait for the 70k power bonus (the samurai looking armor) .. well that's only my opinion about that and still, its up to you if you wanna get some of your desired clothing ..
