Kelly 28
The Kelly 28 is the everyday Kelly — large enough for daily essentials, small enough for evening, and produced in higher quantities than the 25 or the 32. It's the most balanced Kelly size, and often the first Kelly a collector acquires.
Unlike the more architectural Kelly 25, the 28 in retourné form softens noticeably with use, which is part of its charm. But that softness works against you in storage: without a properly sized pillow, a Kelly 28 will lose its shape faster than a Birkin will. This guide covers the specific storage discipline the 28 needs.
