When you can see a very messy or grubby room in the photo I find it off-putting.
Poor, blurry photos or listings where there is literally 1-2 photos and often not the back of the garment either.
Badly crumpled clothes that have never seen an iron.
No info in the comments ie measurements or not stating that a shirt/blouse is a sheer fabric and is absolutely see-through and unsuitable for work (been stung a few times when the photos made the fabric look thicker).
Items listed as Very Good condition and they arrive stinking of cigarettes and bobbled..
I’ve given up looking much anymore, finding anything decent is like looking for a needle in a haystack.
