HI CJ,
I have shopped at Value Village and the BArgin Shop and like you said had not problems.
I have also shopped at Wal-Mart, before I figured out my sizes. I usually pick up what clothes I want to try one. If know is around I will duck in a the fitting room in the ladies section. Or i take what I want to try on over the men"s ware. I pick up a couple of men"s items put them over the other clothes and go into the mens fitting rooms. One has seemed to noticed or cared.
I have not tired Pennington's +14 or Addition Elle, both do have good web sites
I hope this helps, Happy shopping
Maria
