Where can I get quality

I've been wearing only ladies underwear for over 20 years now... there are a few reasons for this so let me explain... firstly i'm Transgender so i like nice girly panties and my favorite style are Brazilian, but a thong is nice from time to time... Secondly Ladies underwear aren't as bulky as men's and made from lighter material... I Generally buy mine from Marks and Spencer's but have also bought from supermarkets or ebay... I can't say i recognize the issues raised in this thread as mine last for as long i want them for... and as i have a severe panty fetish i buy more every 3 - 4 months and have a purge of old ones every so often just to make space for new ones not to replace worn out ones...
