It's the brand BonBom 26 Summer collection,

and it looks like that is the original fit of the outfit.

3. I can't believe people left thousands of comments on that outfit d*mn ã…‹ã…‹ã…‹ã…‹

4. It looks like a swimsuit with a longer pantie

5. It's f*cking weird, why are they showing the panties ã…‹ã…‹

6. F*cking ugly

7. It just looks like a swimsuit 

8. The photoshoot is pretty but wearing it in real life is a bit..ã…  

9. I've heard all sorts of weird comments made to this outfit 

10. I feel like if they turned the outfit into a mini dress, it would've looked better
