LV can be made in several countries including France, Spain, Italy, Germany, Switzerland, and the US. Italy is most notable for sunglasses, shoes, and even bags while France and Spain cover predominantly bags and SLGs (of course this isn't a precise detailed list but hopefully you know what I mean).
These countries are responsible for covering the global market but because the demand in the Americas was so high LV in Europe couldn't keep up and outsourced production to be local and to produce the most popular designs such as the Speedy, Keepall, Neverfull, Delightful, Totally, etc. (again not a precise detailed list). Occasionally a MIF or MIS bag will become available for sale in a North American store but it's fairly rare and is a result of Europe helping to fill an order...although I've never seen the SLGs MIU before so I have to assume that France and Spain are still in charge of those.
Very informative thank you, explains the differences and why I prob won't see Made in USA in the UK.
