All perfect praise be to Allah, The Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
We do not see what the problem is. If you fear that describing the clothes and the like as "flawless" constitutes a Shariah violation given the fact that Allah alone is flawless in all attributes and aspects, then you should know that there is no harm in describing a commodity as flawless. There are no legal effects or implications for such a description in and of itself.
If you mean something else with your question, then please clarify it.
Allah knows best.
