My load-bearing concern is broader: the manuscript body as provided is unreadable and carries a different arXiv ID, so neither the architecture nor any quantitative evidence can be checked. The prompt's rule to treat appended/corrupted passages as in-scope evidence supports treating this as a serious verifiability problem. I am not alleging misconduct; I am noting that the central empirical claim is unsupported by any legible text. No independent support—code, proofs, or reproducible tables—is present. If the intact PDF is retrieved, the next concrete step would be to check whether the reported comparisons are on standard splits, whether baselines are named and fairly configured, and whether identity metrics corroborate the 'identity-preserving' claim.

What you get is mojibake that carries the header of a physics arXiv submission (2508.08489v2), so there is no readable full text to referee. Everything we know comes from the abstract, which describes a multi-garment virtual try-on framework built on diffusion transformers: a Garment Representation Module, a Person Representation Module, and an A-DiT fusion module that jointly models upper/lower garments plus identity and supports text-prompt customization. The abstract claims state-of-the-art results on VITON-HD and DressCode.\n\nWhat is good: the abstract is coherent, and the problem is real—most try-on methods handle single garments or treat tops and bottoms separately. Prompt-based customization in a shared latent space is a sensible goal. The writing in the abstract is clear enough to convey the intended architecture.\n\nBut none of the claims can be checked. There are no architecture details, no equations, no tables, no ablations, no baselines in the accessible text. The SOTA claim is therefore unsupported, and the novelty looks incremental relative to existing DiT-based multi-garment work; the abstract does not demonstrate a new capability class. The soft spot is not a scientific flaw—it is a submission failure. The appropriate move is to ask the authors for a corrected, readable manuscript, not to review this one. There is also a speculative worry about whether identity cues (tattoos, body shape) survive the joint latent space, but without the method text that is only a guess.\n\nI would not send this to peer review as-is. A referee cannot evaluate evidence that is absent. If a corrected version appears, the area is active enough and the combination plausible enough that it might deserve a look. For now: desk reject with an invitation to resubmit after fixing the full text.
