This is a perfectly good sticker collection and if you buy it I'm sure you'll be happy with it. However as my family have tried a lot of different sticker collections, I'll give you my opinion of this one VS some others so you can decide if this one is right for you.
We bought this product as the fashion page in
Melissa & Doug Sticker Collection - Pink had been such a hit with my four year old and we expected this to be more of the same. It is isn't. These stickers are much larger (approx 6 girl stickers fit side by side on a horizontal piece of A4 paper as opposed to approx 12 in the pink collection) For our purposes, the smaller stickers were more useful for decorating objects with. We also found that these ripped easier than the smaller ones when peeled by clumsy young hands. These stickers don't have a huge amount of variety either (For example the girls look very similar to each other). And we found the pink collection to be more versatile as it has fashion stickers as well as other kinds of stickers (For example fairies, princesses, ponies and pets). I would recommend the pink collection over this one if you want some stickers for general use as well as dressing up ones.
If you are mainly interested in the dressing up aspect of the stickers, then I can't recommend the Usborne sticker dolly dressing range highly enough.
Dolls and Ballerinas: Usborne Sticker Dolly Dressing is one of a large range. (You can often get Amazon warehouse deals on them so you can pick them up for around £2.50 each.) These are A4 size as opposed to the A3 size Melissa and Doug range, so the Usborne ones are easier to store and travel with etc. The Usborne books have pages of girls in their underwear and a page of stickers for each scene. Each page has a basic story to it and they do some that are educational (Eg historical and world costumes) and some for boys (Knights and pirates). A downside of the Usborne books are that you need one book per child (The Melissa and Doug collection are easy to share.)The only other downside for me is that my daughter wants to keep them as story books after she's completed them, but I'm sure for people with more space that wouldn't be an issue.
One other sticker collection that we've had and loved is
Djeco 1000 Stickers for Little Ones. It was more expensive, but the stickers are thick and glossy and none have ripped yet. These stickers are too good to use on any old project, but are ideal for decorating toy storage boxes etc with and also are good enough to make birthday cards from. There's no dressing up stickers in this collection but there is a selection of heads to be put with bodies so you can have a mermaid's body, cowboy's head combo if you so wish. The Djeco sticker collection is a truly unisex set and ideal for sharing as you get two copies of each page. The downside is the price, and the fact that you might have to police their use.
In conclusion, this collection is fine and I'm sure your daughter will like it, but in my personal opinion there are better options out there.
