I finally purchased a half-wig I've been wishing to do so for a long while but haven't due to worries that I will look too wiggy. After going through many reviews on hairsisters and watching videos on youtube (mainly from muffinismylovers) I decided upon Lorena (HZ 7054):
This is synthetic hair it cost £13.99 around $22, I purchased it from pakcosmetics.com with £2 extra for postage and packaging. This wig is available for $19.99 from hairsisters.com, it's funny that if I go to my local BSS they sell these synthetic half-wigs for typically £40-£50 :O.
A review and pictures will follow when the wig arrives :)
