Love Guide London except for one major flaw. They go out of stock quickly on many items which I find frustrating. These shirts are not cheap so you'd think Guide would invest in customers by having appropriate levels of stock. This is made worse by stock being advertised only then to see they do not have your size. So, I do check in to Guide from time to time and, if I'm lucky (and it shouldn't come down to luck!) they have a shirt I like in my size otherwise, sadly, I have had to resort to other suppliers that care more for customers in terms of having appropriate levels of stock and availability.
