Heheh dont worry DG...I thought "tback" was meant to be a thong at first also. But I do agree with the comments about the dresses looking like something from miami vice and looking skanky.
As for nails...I also get mine done quite often, but I do it for myself, bc I think they look good. I would have to guess that guys dont like bitten off to the quick short nails...but probably dont care for long long nails...bc if I would be too scared to get poked in the eye (or somewhere else)!
