I've been using my brown leather Blooming Marvellous nappy bag as a handbag for nearly 2 and a half years. 
The zip has half come away and I don't really need the multiple nappy/milk etc. pockets any more as my DCs are 4 and 2.5!
So I need to buy a new one. Having used nappy bags for handbags for the past 4 years I have actually been coming out in a cold sweat every time I've been shopping for one and have come home empty-handed. Oh the pressure of finding something stylish but not too try-hard or young (I'm 37), that is big enough to fit all the paraphernalia required by 2 pre-schoolers, has a shoulder strap and is in universal black or dark brown leather.
I'm happy to spend up to £150.
Help!
