Vintage Ralph Lauren Chaps lightweight cotton trenchcoat style dress.

Beautiful wide lapels draw the eye to the face.

Body is fully lined in cotton and sleeves are unlined. (That's how we know this was

intended to be worn as a dress.)

This garment can be worn as a dress or duster, depending on your preference.

There's a hidden button at the lower part of the dress which keeps it from opening up

too much as you move. (See photo)

Bracelet length sleeves are unlined and have tabs for rolling up. (If wearing as a duster 

this will work best over tank tops due to the sleeves being unlined.)

Knee or just below knee on most.

Vintage size 16, similar to a modern size medium or 8/10
