Lurker here - but I am always on the hunt for cute plus size clothes, so I have to join in. For jeans, I usually buy Levi's from macy.com - they carry lots of good styles and a good range of styles. I also buy a lot of plus size clothes from target online, as many of you seem to do. My local store doesn't carry much, but oddly, or sadly, they have plenty of plus size workout wear. For cute dresses I like alight.com - they have good sales now and then too. For leggings I like Old Navy and I like their yoga pants too - but I do feel the quality isn't worth their prices. For tights and leggings I also like www.welovecolors.com. I find their xxxl to be a good fit - for the record I'm 5'9 and 250lbs, usually a size 20/22/24 depending. Lands End also has good sales. I would never ever buy anything from them at full price because they send a sale email almost everyday. They are good for fancier stuff or investment pieces, like good coats or everyday sweaters. Not the best quality, but decent styles for the sale prices. I find their t-shirt sales to be really good and their bathing suits are no fail. For pretty dresses and formal events, I've had great success with Shabby Apple. I've had to do television spots a few times over the past year and I've been able to get beautiful dresses from them that made me look as young as I fee/am, without being forced to shop at Lane Bryant. Shabby Apple makes me feel modern and I like that. That being said, the only thing I buy at LB is underwear - their clothes seem to be to expensive for what they are, and I resent everything having to be a pattern, as is the case with a lot of retailers who make clothes for plus size women. No patterns please! Also Lord & Taylor and Nordstroms have good online plus size sections and their sales are good. I almost never pay full price for clothes - unless I am investing - which I rarely do. Also, every now and then Talbots has a good sale and their plus size selection is modern and vast.
Good luck everyone!
