I so understand where you're coming from! I hate shopping for clothes because nothing ever fits. I gave up shopping at stores, I now buy all my clothes online, and I've found some awesome companies that have some really nice stuff and their clearance prices are incredible.

Good luck! And if you do decide to get the gastric bypass, depending on how overweight you are, it's totally worth it! I just had it five weeks ago and have lost 33 lbs so far. I feel fantastic, I'm never hungry, and eventually I'll still be able to eat about anything I want, just in much smaller amounts. I wouldn't have considered it when I was only 100 lbs overweight (though that was awful, but I could still walk) but when I tipped the scales at almost 200 lbs overweight, I'd had it, I'd dieted my way UP to that, tried all kinds of diets, even gained weight on some when I was being strictly by the book, exercised my heart out, and never lost weight. I ended up with severe health problems, diabetes, hypertension, sleep apnea, borderline congestive heart failure, always had to use the stupid electric carts in the store, plus a few more. No fun. Today I shopped at four different stores for about five hours and walked the whole way!
No electric cart for me anymore!
Good luck on finding some cool clothes. Sometimes online is waaaay better than shopping in a store, even if you can't try the stuff on before you buy it. You also might check
ebay, as they have all kinds of cool second hand clothes people are trying to sell.
Don't feel bad, all of us on this thread totally understand where you're coming from!
