Coach all the way! But I only like leather bags. I haven't had an interest in any canvas bags by anyone, so that is probably a good thing! I won't spend more than 500-700 on a bag anyhow, and prefer to spend less since nothing lasts forever! Coach has some nice styles and colours that range from neutrals to colourful and just seem perfect for me.
I have gifted my friends Aldo, MK and Coach and they simply loved it. That shows how these designers has an impact on the ladies that prefer carrying their stuff which looks amazingly lush.
I would say MK and Tommy Hilfiger has maintained a very decent market. They work on styles and when it comes to pricing they are appropriate too.
My Givenchy bag is my ultimate big-girl purchase that I don't regret at all. Madewell, Calvin Klein, and H&M (durable non-leather) have some very nice, underrated bags as well. I'm drooling over a Burberry satchel but its waaaaay out of budget.
