Overall, I probably buy from BR more than any other store. I need petites so I shop at the stores that offer them (increasingly and frustratingly online only). I always thought of BR as a dash more trendy than AT, higher quality than ON & LOFT, and better/more consistent fitting than Jcrew (also more my colors - murky summer shades rather than clear spring shades). If I was not so firmly in the petite camp, perhaps I'd shop elsewhere and my closet would be filled with high trends and edgy fashion. Okay not perhaps... very likely.
But designers have made it loud and clear that high fashion is not for short people who are of average build and not razor thin. The best I can do, at 5'0, is modern classic so that's what I wear.
That said I think I missed this BR shift entirely, as we were in the middle of selling our house and moving so I was shopping a lot less....
My favorite BR items are their sweaters. Historically, you could not beat them in that department. As others have said, I still have BR sweaters that are years and years old and holding up just fine. I always hit BR for merino wool in the fall. I have the super thick cashmere they offered maybe a decade ago -- the sweaters no longer fit me but I've held on to them because maybe they will again someday.
Not everything at BR would fit me -- but I loved that they offered various fits for a variety of bodies. Yeah for the Sloans! I just stocked up on several pairs for work.
I also loved BR for the natural, breathable fabrics. I love the way LOFT blouses fit but sadly many are synthetic which just makes me all sweaty.
As for the BR collection lines, I love those and would buy but alas, those are never offered in petites.
