Well... Sometimes it's a brand/quality thing, as in, "I don't know about this <designer> item, do these hold up/run big?" People who comment on the maker/item from personal experience can influence me. Especially with mailorder and especially with questions of suits, it seems, there's bound to be someone who's worn a given maker, whose advice can be useful. Sometimes it's a wearability thing. There's a lot of "shoppers" here, including me. If I see a good deal on a quality piece - for instance, that RLPL overcoat that the Foxx posted yesterday, I'm usually interested, but due to financial limitations, limited. I'd like the item, and think I can pull it off, but sometimes it's useful to put it to a "global test" (ha. ) to just get a reality check on its wearability. On the other hand, I certainly have oft-worn items in my closet that wouldn't have passed a test here, or at least would draw negative comments. People who read past posts can see members' preferences, and trust not to rely solely on, say, ernest's opinion of brown shoes. I think style forum opinions can be useful, but are no gospel. Edited to kill a smiley.
