Hello Everyone! A Quick Question If I Might.

[nerdyandquirky.livejournal.com]

I'm just getting into Sweet Lolita, and was interested in this dress here: http://www.my-lolita-dress.com/beautiful-sweet-lolita-op-dress-yuan-36

Now, they don't have a brand for this dress, nor can I find any reviews surrounding it at all. They also don't have it in blue (I don't like the Pink or Yellow) so I also found it here: http://www.lolitadressesshop.com/sweet-party-cotten-lace-prom-short-sleeve-knot-op-lolita-dress-p-3227.html

I really like how it looks, but wanted to know what you guys think! Should I go for it? Does it look like a good buy? Does anyone have experience with this particular piece? Thank you very much!

EDIT: Apparently the colouration I'm looking for is actually called mint, and is the first one you see in the pictures. Also I found where the dress comes from, Taobao. Here is the original product: http://item.taobao.com/item.htm?spm=a230r.1.14.206.u2jKvY&id=39382536643&ns=1&abbucket=18#detail

So, new questions. Which store should I use to buy it? Should I get it from Taobao directly? And still, should I buy it at all?
