clothes for plus size woman on a budget?

I am very insecure about going to places and shopping for clothes in plus size due to none of it ever fitting right. The ONLY place I shop is Torrid because they have beautiful, sexy clothes that fit perfect....and if any of you shop there, you know 100 bucks gets you 1 shirt and a pair of jeans. My husband and I are taking a vacation to Florida in September and we are on a tight budget for any extra clothes and whatnot.. I'd like a few nice outfits that won't cost a few limbs. Any advice on where I can shop for cheaper but nice clothes as a plus size woman? Thank you!!!
