Hi Anchie --
Not much advice for you but I wanted to grouse about the sweater situation too. Like you I'm a sweater person year-round; if I'd lost 4 sweaters this season like you I'd be such a pain!
Could the BR ones have caught on rings, belt buckles, employee name badges -- anything like that? Or something in the wash? [Is the hole in the light-colored one down at the cuff? If so, I'd be tempted to do a quick darn and fold the cuff back. That orange one, though...tough placement!]
BR knits are very hit-or-miss IME. I have the crewneck merino from a couple of years ago and they've been fine (boring layering pieces). It's the Ann Taylor 100% merino scoopnecks of eons ago that I really miss but I have some 2nd hand Uniqlo merino that look pretty good -- and the owner wore them a ton. Basic, though.
Hopefully the ideas everyone posted above will get you fixed up. UK-based Pure Collection comes to mind as a possibility but IDK if the styles would appeal. Maybe United Colors of Benetton for something in the lower price point that's a little more zippy than Uniqlo?
I really wanted some semi-statement but NOT patterned sweaters this year after a few years out of the sweater rat race but...ugh. I can do blousey + narrow sleeve, slouchy-sleeved + narrow body, or narrow + narrow. The all-over big is just terrible on me, period.
After a very frustrating look -- buy -- return cycle I ended up with a couple I love* and a couple that will do. And putting a few that I'd demoted to weekends back into play out of desperation.
Good luck with the hunt!
* for those in the shipping zone, I tried Century21 online -- c21stores.com -- for the first time and that was my overall best (out of Boden, Bloomingdales, Lord & Taylor, Nordstrom & the Rack, more I'm deliberately blanking on...
