They wore these outfits only a few times (at least Sohee’s pink 8 top).
The official title for the broadcast performance on 2007.09.16 was 전국 기능 경기대회 축하쇼 (National skills competition celebration show) but most pics are from a university festival.
The following pics are all from the Daegu Haneui University performance on 2007.09.11. 원더걸스 대구 한의대학교 텔미 공연 직찍
First ones are by parkozen_kei96311/흐르는강물처럼 who was as awesome as to send me his/her (almost) complete collection of photos in full-size!
The next pics are also by the same photographer but sadly they weren’t included in the collection of full-size photos.
The gif seems to be a compilation of the photos of Sohee during her dance break and the bridge part but not all of those were shared as actual photos.
Anyway there are some more pics! Next ones are by 호마지 from the SLR Club.
Next pics credit to 023457 as tagged. I don’t know the actual blog or whoever uploaded these.
The next pics are untagged and I don’t remember where I found them either but I guess they are all from the same photographer looking at the lighting and the positions..
Next couple of pics of Sohee are from 클로버
And some more untagged photos
Now some photos of Wonder Girls backstage with fans also on that Daegu University Event. Found all those on Korean sites like Daum, Naver, Nate and so on.
Next we have some photos that are from that Korean Congratulation Show. First batch is by 우울안소희 from the official WG daum cafe
And lastly one more big pic by emma:) but I don’t know where they posted it so can’t check if there are more..
