If we’re supposed to take the OT verses on attire literally, then we should probably all be wearing robes.
Assuming you’re not actually cross-dressing, I think it’s more important to dress modestly than to worry about the exact nature of the garment being worn. There are some very modest slacks and tops, and some very immodest dresses.
I think the same applies to men, by the way. Men often yap about how “visual” they are, and women need to dress modestly, but men don’t. Well, from my point of view, an immodestly-dressed man is a
near occasion of sin.
By the way, please exucse my men’s socks, shoes, and gloves. When you’re a woman and have big hands and feet, you sometimes have to do your shopping in the men’s department. Same goes if you’re very tall.
