I just received my first PukiPuki this week and after trying on several wigs, including a Fairyland wig, I began searching Monique wigs for something in a more suitable color and style. The size 4 wigs from Monique had both fit, but I wanted something shorter and, if possible, less full. (The Fairyland wig is loose, a common problem.) In the process of wading in to their site, (anyone who has shopped there knows what I mean), I discovered a size RD4. It was listed after the 3 1/4 and before the 4. Did this mean it was somehow between sizes or what? Well, after reading most of what I found on the net concerning size RD4, I discovered no one really knew and that asking Monique was the only course of action. (Sometimes we're a wee bit impatient for answers) It turns out the the RD4 is a deeper wig, kind of like buying a size 5 and taking it in to fit a size 4. Good to know, but not what I needed. I'll be doing more searching, but in the mean time here he is with a black grass skirt and flower lei. I really like my Luau set and my new camera!
