I always note the marked size of the apparel but do my best to get most listings with measurements as well. Please see measurements and sizing photo if there are questions as to process and impact on correct sizing. Most come out fairly similar but vintage clothes can be much smaller than their modern brethren.
*Note - photo with sizing is estimate dimensions - measure a shirt of your own that you know fits well for more accurate needs.
Shipping as noted below and I do combine shipping - please advise of items and I will provide quote however most will be added with no additional charge.
