Given that I only have small windows of opportunity to do some cd wamming buying and finding clothes can be a nightmare before disposing of them and covering my tracks. As well as watching the pennies in my pocket. Recently I've been looking into turning old clothes into female clothing I.e t shirt into a skirt. Just wondering has anyone else tried this?

The first few things I dressed up with where homemade- cutting underpants to make bra and thong, cut and stapled t-shirt to make a swimsuit, ball up some socks to make boobs etc...

They did the job at the time, but nowhere near as good as regular clothing. Keep a regular search on eBay/Amazon and you can find some decent bargains (click and collect too).
Sales on Ann Summers/LoveHoney and also be good.
If you're not feeling confidant about browsing IRL shops; write your sizes on a scrap of paper and constantly refer to it- you'll look like you're buying for someone else.

For discreet cleaning I wear clothes in the shower. Most the rinsing out I can do as I'm washing off after wamming, then sneak them into a normal shower if they need extra.
Underwear and simple clothes (swimsuits) are usually recoverable to the point of being usable again, long dresses may need more than 1 machine wash which is a lot harder to pull off.

Thanks for the advice. For me in the short gaps I have from purchasing using then disposing off is hardly efficient or cost effective so I'm trying to find alternative ideas. This might sound naive of me as I don't really do a lot of online shopping apart from amazon. Which places do the most suitable click and collect?

Amazon, eBay, and Lovehoney I've personally used for click'n'collect- you can select the collection option at checkout and choose from the nearby pickup points, mostly local shops/post office/supermarkets and Amazon lockers.
Some delivery companies can divert to a pickup location too if you use their app.
(not all Amazon/Ebay sellers offer this, but a lot do- you'll see it on the individual item listing. Ebay has the option to filter searches for free c'n'c, and 99% of items marked as Amazon Prime can be collected).

One other thing you can do on Amazon is save a wishlist of the clothing you'll like to buy, then wait for the old "try a week prime for 99p" offer to roll around; buy the offer, get a sizable chunk off the delivery fees and immediately cancel your membership.

Thanks for the ideas. You've given me something to think about for sure
