Shopping Do Alice's Collections wigs match picture quality?

AC is a dealer so it's going to vary by the wig.
But I have the first one that you linked which is by Msiredoll, and it looks exactly like the pictures. So soft and pretty. I can't recommend it enough So I'm certain the other Msiredoll wig in your second link would be beautiful too, since it's by the same maker.

 

Like mentioned above, AC is just a dealer, so the quality will vary.

Just wanted to add that I ordered a styled Msiredoll wig through them a long while back and was quite disappointed actually... it had a side part just in the front and that bit was a large hard chunk of glued together wig hair that doesn't quite sit right on my doll's head.

That said, the style you linked should be fine, as it's still a pretty basic style. Just avoid the slightly more complicated styles.

 

I bought the black version of the first wig you linked for one of my girls a few years ago and it was exactly the same as in the pictures

 

Most of them are of decent quality. Acbjd had selected these wigs from various shops on Taobao, I'm using some of them too ( Bought direct from taobao though)

I got only one wig from them so I can’t speak for all but mine was not the same at all. But for the low price I paid, I don’t even feel bothered much. The wig I got is short hair mohair wig. What was not discribed was that the entire wig is made of “fur fabric” and hair has very obvious parting line which is a seam line and does not appear of promotion photo. I could list more about it. I think they could put better description on some items they deal. I haven’t bought many items I have been attracted to due to lack of details.

 

It tends to be 50 / 50 for me, but as people said the low prices sort of make the disappointment easier. Part of the problem on my end is that most of the pictures are on dolls larger than mine, much larger in some cases, and that throws off the whole style when they try to minimize it.

 

I like to search the original store on taobao and see owner pictures in reviews. Msiredoll is a known brand so it's easy to find and recognize thanks to the watermark, and their wigs usually have quite some reviews, unless the wig is newly released.
Here's the link to the store.
Here's another link to the first wig you linked.
The biggest challenge here is to navigate the chinese site which is not easy even with google translate because it often translates into nonsense.

 

I just received two MSireDoll wigs I bought from Alice. I'm very happy with them.

 

I have the second one you linked and it looked exactly as pictured. I think they're fairly reliable.

 

I have ordered MSire wigs several times, and they're always gorgeous!

The cheaper wigs....not so much. I ordered a blond/pink one from Alice (it was in the $10-15 range on sale) and the quality was horrible. It had bald spots and the fiber was not silky or shiny. It was so bad, I actually contacted Alice about it, and she removed the listing and let me pick a different wig of the same value. The second one, while far from high quality, was reasonable for the price.
