Everyone seems to have the same problem when deciding what size clothes does my doll wear. I am not a pro, however I have taken my best guess a few times and here is what I found to be a big help. Here are 2 sizing charts that seem to work good for me. Also keep in mind the majority of dolls are made across the pond where small sizes are the norm unlike here in the USA, also many figures are derived from sculptures rather than cast from real people, so sizes are "dreamed up", (aka, huge breast, extra small waist, huge butt) Many dolls are very short almost like child size, so child sizing charts may prove to be more helpful. So you might have to get use to hunting for clothes in the children's section of clothing. So as far as sexy clothing you may be out of luck, unless you know how to sew. However, not all is lost, costume shops and the like may be your answer. Cosplay shops offer such outfits, be prepared for "sticker shock" when it comes to price. Another and low cost alternative to this is the local "goodwill" store. Mix and match from the selection they often have using the sizing charts I have posted below. For example pants, and shorts can sell for say $2 or $3 each, tops can be similar pricing, dresses can range $5 to $15, shoes can be low priced as well from 50 cents and up a pair. A plus to buying clothes this way is fading of colors has already taken place so less chance of color bleeding onto your doll. A word of warning sometimes you can get unwanted extras, so take normal precautions washing, and drying before using. With all of that being said here are the sizing charts.
