Hello, Both the HAC and the Birkin come in different sizes... lets just zoom in on the handbag sizes their are also travel versions of each
The Birkin will have longer handles than the HAC,
Birkin 35cm verses HAC 32cm> The HAC 32 in TOGO will be less floppy than a Birkin 35cm, The HAC 32cm will be 6 inches deep verses the 35cm Birkin at 7 inches deep, The HAC 32 will appear Taller than the Birkin 35cm. Also the Hardware on these styles is different the HAC has square turnlock JPG hardware and the Birkin has a round turn lock closure. Their are pluses for each bag... The HAC 36cm is Taller than the Birkin 35cm the handles are slightly shorter and the bag is deeper by .5 inches. I hope this helps :o)
The HAC (the original birkin) also comes in a 28cm which I have, and I love it. It is best described as the north/south style of the birkin with shorter handles. Birkin- again, the sizes 25cm, 30cm, 35cm, 40cm.
Pro of the HAC- longer and more elegant. Fits documents quite nicely.
Cons- the handles. Some have a real problem with the handles, whereas others don't at all (like me). You will find that with a HAC you will primarily carry it hand-held, but I also carry mine in the crook of my arm.
One great thread is the "All Hail the HAC" thread here:
You will get a great idea of why so many of us love the HAC. I love the fact that it is a little different than the typical birkin and makes it more unique. But all in all, it comes down to personal preference and whether or not you like the particular shape.
I'm still undecided about whether or not I like the HAC; I wanted one for ages until I saw one IRL and I didn't really like the way it looked, but I think maybe that was because it was so large... What sizes does the HAC come in, again?
