This is in no way an unique post, in fact it's been done many times and I relied on the information in other people's posts myself in the past, so I'm only adding my contribution to the beauty world, sharing my experience with foundations I found that have a very light shade and that I was able to get one way or another here in central Europe. We don't have anywhere near the selection you can find in North America or Asia, we don't even have the selection that's sold in our neighbouring countries. In fact, if you're looking for a very pale foundation in Slovenia, right now, you can buy very little of them, unless you're buying online. Most of mine are drugstore and I buy them in various types of undertones, finishes and coverage levels, so I hope you find my contribution helpful. I have full reviews of all foundations linked in this post, so you can read about them in detail and see the before/afters.
At the end also I added a list of all other very pale foundations that I was able to find, but I haven't tried them either because I can't get them at all, or I haven't had the opportunity to try them or they are too expensive (I noticed during making this post, it's not cheap to be pale). If you have any other recommendation, please share in the comments, you'll be a great help to me and other readers.
