That depends on which version of Tifa you want to cosplay; original game or Advent Children or even Young Tifa as depicted in Crisis Core.
The AC look is most popular, so I'll outline that. This list is only partial, and every cosplayer has to choose their own pieces.
A mid-back-length black, straight, wig,
A leather sleeveless zip-up top,
Black shoes with white toes,
Black or leather shorts,
Another piece of leather for around the waist, (I recommend looking at pictures for this one.)
A pink ribbon for the left arm,
A padded bra.
For more detail, I would recommend looking at pictures of her from the Advent Children movie or whatever game you wanted to cosplay.
I would say Vanille from Final Fantasy 13, or Aeris or Tifa. The Tifa costume I would recommend to be the Advent Children costume because the FF7 one is a little showy. (Personally I would like to be Tifa)
try Ebay, there is alot of cosplay items available there
Ebay.com or Amazon.com
It entairly depends of the cosplay. But in most of them, yes you do.
I guess you could pair her with anybody.. so here goes... Tifa x Cloud Tifa x Vincent Tifa x Barrat Tifa x Reno Tifa x Rude Tifa x Tseng Tifa x Rufus Tifa x Hojo (BORRK!) Tifa x Sephiroth Tifa x Cid Tifa x Aerith Tifa x Yuffie Tifa x Kadaj Tifa x Yazoo Tifa x Loz Tifa x Zack >.< that's all I can think of right now... xx
